    Boron nitride and its development history

    What is boron-nitride? Boron Nitride is a crystal made of nitrogen atoms, boron atoms. The chemical composition of Boron nitride is 43.6% Boron and 56.4% Nitrogen. There are four types: hexagonal boron Nitride, rhombohedral Borodure (RBN), cubic boren nitride [CBN], and wurtzite boron Boron (WBN).
    The history of boron-nitride
    Boron nitride More than 100 years have passed since its invention. It was used in high-temperature lubricants as a hexagonal boron nutride. Its structure, as well as its properties, are very similar to graphite. This is why it is also commonly known by the name white graphite.
    Boron Nitride (BN) ceramics was first discovered in 1842. Since the Second World War, a lot has been done abroad on BN materials. It was not developed until 1955, after the hot pressing process was perfected. American Diamond Company, Union Carbon Company were the first companies to start production. In 1960, they had produced more that 10 tons.
    R*H*Wentrof produced CBN in 1957. General Electric Company sold Borazon as a product in 1969. The United States introduced CBN tools in 1973.
    Japan imported technology and CBN tools from the United States in 1975.
    1979 saw the introduction of the pulsed Plasma technology, which was used for the first time to create a collapsed cBN film at low temperature.
    To prepare cBN films, people were able use several methods of chemical vapor deposit (CVD), as well as physical vapor vapor (PVD), at the end the 1990s.
    China sees development as a leap and bound. The initial research on BN powder started in 1963. It was then developed successfully in 1966. It was finally put into production by 1967.

    The physical and chemical characteristics of boron-nitride
    Physical properties
    CBN crystals are usually dark brown or red with a zinc mix structure and good thermal conductivity. CBN is hardier than diamond and is used in a variety of applications, including as abrasives and tool materials.
    Boron Nitride is chemically inert and can be corroded by water and organic acids. The hot concentrated alkali breaks the boron/nitrogen bond. Above 1200 it will begin to oxidize. It starts to decompose around 2700degC in a vacuum. It is slightly soluable in hot acid but insoluble when dissolved in cold water. The relative density is 2.29. The compressive strength is 170MPa. The maximum operating temperature in an oxidizing environment is 900 degC, while it can reach 2800 degC when inactively reducing. However, the lubrication performance at room temperature is poor. The majority of the properties of Boron Nitride are superior to those of carbon materials. Hexagonal Boron Nitride has a low friction coefficient and good high-temperature stability. It also has high thermal resistance, high strength, low expansion coefficient and corrosion resistance.
    Material structure
    Hexagonal graphite nitride crystals are the most popular. There are also amorphous forms. In addition to hexagonal crystal forms, boron nuitride also has other crystal forms such as cubic rhombohedral and boron Nitride (r-BN), Boron nitride (c-BN), wurtzite type boron nitride (w-BN). Even graphene-like two-dimensional boron nutride crystals were discovered by people.

    Vanadium-nitride (or VN) is a mixture of vanadium, nitrogen. It is a dark cubic crystal powder having a molecular mass of 64.95.
    Vanadium nitride is used to increase wear resistance during the nitriding of steel. VN can also be used to form V2N in the nitriding of steel. VN has a cubic rock salt composition. Also, there is a cryogenic version that contains V4 Clusters. Dynamic instability occurs when the energy in the vibration mode of the high temperature NaCl crystal phase phase drops below zero.
    It is a strong-coupling superconductor. The potential for supercapacitors is attributed to nanocrystalline vanadium. The stoichiometry determines the properties of vanadium-nitride.

    Vanadium nitride, a new alloy additive, can replace ferrovanadium for the production of microalloyed stainless steel. Vanadium Nitride can be added to steel to increase its strength, toughness, ductility, thermal fatigue resistance and weldability. The addition of vanadium-nitrogen alloy to steel can improve the strength and reduce the cost of vanadium by between 30-40%. Vanadium-nitrogen alloy can be used as structural steel and tool steel. Vanadium-nitrogen alloy can be used in high-strength low alloy steel to produce effective vanadium/nitrogen microalloying.

    What does Vanadium Nickel VN do?
    Vanadium Nitride is a superior steelmaking additive to high vanadium Iron. The nitrogen content in vanadium iron nitride can encourage the precipitation and finening of vanadium. This will make it more useful as an additive for steelmaking.
    Useful for the production of semiconductor films that are wear-resistant or resistant to corrosion.
    It is a novel and effective vanadium alloy addition that can be used in the production of high strength low-alloy steel products, such as high strength welding steel, non-quenched tempered steels, high speed tool steels, and high quality pipeline steel.

    What is Silicon Nitride?

    What is it? Silicon Nitride ? Silicon nitride can be described as an organic substance that has the chemical formula Si3N4. It is an important structural ceramic material, with high hardness and wear resistance. It is also resistant to heat and cold shock. It can be heated to over 1000°C in the air. If it is quickly cooled, it will not break. This is because of the exceptional properties of silicon-nitride ceramics. It is used often to produce mechanical components, such as bearings. The heat-receiving area of engine components can be made from silicon nitride clays, which are heat-resistant and hard to heat transfer. This will not only increase the quality of the engines but also save fuel. Similar engines have been created in China and Japan.
    Silicon Nitride's main features
    The relative molecular weight is 140.28. You can choose from grey, off-white or white. It is high temperature insoluble, has no melting points, and has strong resistance to high temperatures creep. The melting point of reaction sintered silicone nitride is over 1800°C; hexagonal system. The crystals are hexagonal. Si3N4 prepared through reaction sintering methods has a density of 1.82.7g/cm3. Si3N4 made by hot pressing method has a density of 3.123.22g/cm3. Mohs hardness 9.9, Vickers hardness 2.20, and microhardness 3.123.22g/cm3 are the Mohs hardness. Melting point 1900 (under pressure). Normal pressure usually causes it to decompose at around 1900°C. Specific heat capacity 0.71J/g*K The heat of forming is -751.57kJ/mol. The thermal conductivity of the material is (2-155) W/(m*K). The coefficient of linear expansion is 2.8~3.2x10-6/(20~1000). It is not soluble when water is used. Soluble in hydrofluoric acids.

    Hexagonal Boron Nitride is 10 Times Stronger Than Graphene

    Hexagonalboron nitride is a two dimensional layered broadband gap insulating material that exhibits good heat resistance, chemical stability, as well as dielectric properties. It is widely used for electronic devices.
    Hexagonalboron nitride has a structural similarity to graphene. It is composed of a planar network of atoms interconnected in hexagons. The only difference between graphene and H-BN is that all atoms in graphene are carbon. In H-BN, every hexagon contains three nitrogen and three boron molecules.



    H-BN is theoretically more powerful than graphene because of its strong carbon-carbon bonds. The strengths and elastic modulus for the two materials are very similar. H-BN is slightly less than graphene, which has a strength of 130GPa and a young's module of about 1.0TPa. HBN's strength, however, is 100GPa and 0.8 tPA respectively.
    Graphene, despite its exceptional mechanical properties is very brittle.

    British engineer Griffiths published in 1921 a theoretical study on fracture mechanics. This included a description of the failures of brittle materials as well as the relationship between the size cracks and the force necessary to make them grow. Engineers and scientists have used this theory for hundreds of decades to predict and determine the toughness of materials.
    In 2014, Professor Jun Lou and his Rice University team discovered that graphene has a high degree of fracture toughness. This corresponds to Griffith's theory about fracture mechanics. Cracks are formed when graphene's stress exceeds its force keeping it together.
    Due to its structural similarity with graphene H-bn could also be vulnerable. But this is not true.

    H-BN is 10x more ductile that graphene, according to scientists.
    Professor Jun Lou, Nanyang Technological University Singapore and Prof. Hua Jian gao, of Rice University found that HBN was 10 times stronger than graphene for cracking resistance. This discovery is in direct contradiction to Griffith's fracture theory. Such anomalies have never before been observed in two-dimensional materials. The Nature article entitled "Intrinsic Toughening in Hexagonal Boron Nitride" published the related research results.

    Mechanism of H-BN's Extraordinary Strength
    The team applied stress on the HBN sample using scanning electron microscopes, transmission electron microscopes, and other tools to discover the cause. The mystery was solved after over 1,000 hours of experiments, theoretical analysis and further research.



    H-Bn graphene and graphene are structurally identical, but the boron atoms and nitrogen atoms differ. HBN also has an asymmetric arrangement in hexagonal lattice. This is in contrast to graphene's carbon hexagon. Graphene's cracks tend to penetrate the symmetrical hexagonal structure, opening the bond like an open zipper. H-BN has a hexagonal structure that is slightly asymmetric, due to the stress contrast of boron with nitrogen. Because of this, cracks can bifurcate and form branches.
    The crack that splits means it's turning. To make the crack harder to propagate, this steering crack needs additional energy. H-Bn is more elastic than graphene.

    H-BN's excellent heat resistance and chemical stability have made it an important material for two-dimensional electronic devices and other 2-bit devices. hBN's toughness makes them an ideal choice for flexible electronic. This is also important for the development and use of flexible 2D materials in two-dimensional electronics.
    Future uses for h-BN include electronic textiles that are flexible and electronic skin, and implantable electronics that connect directly to the brain.

    Silicon Nitride Ceramic Preparation And Application

    Silicon nitride Ceramic is an organic material ceramic that doesn't shrink when sintering. Silicon nitride is extremely strong, especially when hot-pressed. This is why it is considered one of the strongest materials on the planet. It has high strength and low density.

    Silicon Nitride Ceramic Preparation

    Si3N4 ceramics can be prepared using a variety of methods, including hot pressing, atmospheric, pressure, and hot press sintering.
    Reaction sintering method (RS)
    It follows the standard forming procedure. First, the silicon powder must be pressed into a desired shape. Then it will go into a nitriding furnace to undergo pre-nitriding or partial nitriding before being sintered. The pre-nitrided green bodies already have a certain strength. There are many mechanical processes that can be done to the green body, including turning, milling, and drilling. To obtain a product with minimal dimensional changes, the temperature must be above the melting points of silicon.

    Hot Press Sintering
    It uses Si3N4 Powder and small amounts of additives (such a MgO or Al2O3, MgF2, F2O3, etc.). It is pressed at above 1916 MPa, and heated to 1600 degrees for hot press molding or sintering. Si3N4 ceramics made by hot pressing are superior to those of Si3N4 that has been reaction sintered. They have high strength and density.

    Atmospheric pressure-sintering method (PLS).
    To increase the pressure in the sintering nitrogen atmosphere, it uses Si3N4's properties to raise the decomposition temperatures (usually at N2 = 1, starting at 1800degC). After atmospheric sintering has been completed at temperatures between 1700-1800degC and then air pressure sintering can be done at temperatures between 1800-2500degC.

    Method of air pressure sintering (GPS).
    At a pressure of about 1-10 MPa, the air pressure sintering silicon nitride takes place at temperatures of approximately 2000degC. The high nitrogen pressure prevents silicon nitride from decomposing at high temperatures. It is possible to produce a high toughness ceramic by using high temperature sintering with less sintering tools.

    Silicon Nitride Ceramic Application

    Silicon nitride Ceramics have exceptional mechanical properties, wear resistance corrosion resistance and other outstanding properties. This makes them widely used in many industrial areas such as metallurgy machinery energy and energy: semiconductor, chemical, aerospace and so forth.

    Silicium nitride ceramics in mechanical engineering can be used to produce bearings. Cutting tools, high-temperature bolts. Drawing dies. Ball valves. Plungers. Sealing materials. Nozzles.

    Hot-pressed silicon nitride ceramic tool have a 5-15x higher durability than cemented carbide and a 3-10x higher cutting speed. Dispersion strengthening can be used to increase the performance and longevity of silicon-nitride tools by compounding TiC or ZrC.

    Silicon nitride clay has excellent mechanical properties. It is both wear-resistant and self-lubricating. It is a good bearing material with a longer service life than other ceramic ones. It is resistant to corrosion and high temperatures, and can be used in harsh environments.

    What is Aluminum Nitride AlN Powder?

    Introduction to AlN Powder Aluminum Nitride Aluminum nitride is a covalent bonds compound. The chemical formula for AIN is It is an atomic nitride crystal that belongs to the diamond-like hexagonal system. The crystal has a wurtzite crystal structure.
    Aluminum nitride This synthetic mineral isn't found in nature. AlN's crystal structure is hexagonal, wurtzite, type. It offers low density (3.2g/cm3) and high strength. Decomposition takes place at 3060.

    Aluminium Nitride Powder AlN Powder - Physical Properties
    AlN stays stable above 2200. At room temperature, AlN has a high strength and decreases in strength with temperature. AlN's thermal conductivity is high and it also has a low thermal extension coefficient. This makes it a great heat shock material. AlN is a great crucible material to melt and cast pure iron, aluminum or an alloy of aluminum. Aluminium nitride has excellent electrical insulation properties. Aluminum nitride is also an attractive electrical component. It is protected by ion implantation through annealing thanks to the aluminum nitride coat on gallium arsenide. Aluminium nitride also acts as a catalyst in the conversion of hexagonal to cubic boron nutride.
    It is slow to react with water at room temperatures. The aluminum powder can be made from ammonia, nitrogen or aluminum at 8001000. This product can be described as a grayish-blue to white powder. Gray powder can be obtained by using the al2O3C–N2 system reaction synthesizer at 16001750. You can also use aluminum chloride as ammonia gas. By vapor deposition, the AlCl3/NH3 system can be used to synthesize the coating.

    In summation:
    1. A high level of thermal conductivity (about 325W/m*K), that is very close to SiC or BeO, but more than 5x higher than Al2O3.
    2. Excellent electrical properties (eg, dielectric constant, dielectric loss, body resistivity, dielectric strength);
    3. High mechanical property. This ceramic has a higher flexural strength than Al2O3 or BeO ceramics and is easily atmospherically sintered.
    4. High optical transmission qualities
    5. Non-toxic.
