    Hafnium diboride applications and characteristics

    What is hafnium Diboride Powder? Hafnium Diboride is an ultra-high temperature ceramic that is made from hafnium, boron. It is a unique ceramic with high heat conductivity and conduction. It is a metallic gray color. Hafnium dioxide has a hexagonal structure and a density 10.5 g/cc. It can melt at approximately 3,250 degrees Celsius. Hafnium diboride's resistance to oxidation is affected by temperature and pressure. At 1500degC and 1atm, having forms an oxide protective scale. HfB2's antioxidant activity decreases when temperatures rise above 1600degC and pressure drops below 1atm. In these conditions, B2O3 (one the oxidation products from HfB2) boils at a higher temperature than B2O3, creating a protective layer of oxide.
    Uses of hafnium diboride powder
    Because of its strength and thermal characteristics, HfB2 can be used in ultra high-speed reentry aircrafts, such as an INTERCONTINENTAL missile heat shield or pneumatic front. HfB2 has an aerodynamic form and doesn't ablate upon reentry, unlike polymers and composites.
    Hafnium Diboride is being considered as a new material to be used in nuclear reactor control rods.
    It is also being investigated as a diffusion shield for microchips. If the barrier is correctly synthesized, it can be less than seven nanometers thick.

    What is Hafnium Carbide HfC Used For?

    Hafnium carbonide (HfC), a grayish, black powder with a face-centered cubic shape, is also known. It has a very low melting point (3890) and is therefore a good material to use for the lining of high melting crucibles.
    Hafnium carbonide has a high elastic coefficient, low thermal conductivity and good electrical and/or thermal conductivity. This makes it a great material for rocket nozzle materials.

    For what purpose is Hafnium Carbide HfC used?
    Hafnium carbonide is a ceramic material with high temperature and oxidation resistance. It also has the advantages that it is low in thermal expansion and electrothermal conductivity. Hafnium carbid is used for the manufacture of rocket nozzles, wingfronts and other critical components. This material is mostly used in aerospace, industrial ceramics, and other fields.

    Hafnium carbide is hard, can be used to add cemented carbide, and can form solid solutions with many compounds (such ZrC or TaC). It is used extensively in the production of cutting tools and moulds.

    Hafnium carbid has a high elastic coefficient, low thermal expansion coefficient, and good electrothermal conductivity. It is therefore suitable for rocket nozzle materials. It can also be used to make nozzles, high temperature linings, and arc or electrolysis electrons.

    Hafnium carbid has excellent solid phase stability and chemical resistance. This makes it ideal for high temperature environments. The field emission performance can also be improved by vaporizing HfC film on carbon nanotube catathode.

    The ablation resistance can be increased by adding hafnium-carbid to Chand C. Hafnium carbonide is widely used in high-temperature materials due to its excellent chemical and physical properties.

    How hard is Hafnium-Carbide HfC?
    Hafnium carbonide has a high hardness (>9 Mohs). HfC can only be used in limited circumstances due to its high cost and technical complexity.

    What is Hafnium, and How is it Used?
    Hafnium can be described as a shiny, silver-gray transitional metal. It was first discovered in 1923. Hafnium is rarely dissociated in nature but can be found in zirconium mineral at concentrations up to 5%. Actually, hafnium and zirconium are very similar in chemistry so it is difficult to separate the elements. Most hafnium that is commercially available comes as a result of zirconium reprocessing.
    Hafnium is earth's 45th most abundant element. It accounts for about 3.3 parts in million (ppm), of earth's crust. Hafnium can resist corrosion due to the formation an oxide film on its exposed surface. It is indestructible to water, air, bases, acids, except hydrogen fluoride, and it does not react with oxygen.

    Hafnium's remarkable corrosion resistance and high neutron absorbency make it an ideal material for nuclear submarines and control rods for nuclear reactors. This is key technology in maintaining fission reaction. The control rod prevents the fission chain reaction from accelerating out of control and keeps it active.
    Hafnium is used to make electronic equipment like capacitors and cathodes. It also makes ceramics, photographic flash, and bulb filaments. It can be used to bind to vacuum tubes and remove trace gases. Hafnium is often alloyed to other metals like iron, titanium and niobium. Examples include aerospace applications like space rocket engines, which use heat-resistant hafnium/niobium alloys.
