Introduction to silicon carbide products
Silicon carburide also known by the names moissanite, emery or coal coke, is an organic substance with a formula of SiC. It is produced by a high-temperature resistive furnace using raw materials, such as wood chips, quartz sand or coal coke. Salt is required for green silicon carbide. In nature, silicon carbide is found in the rare mineral moissanite. It is also called gold steel or refractory grit. In China, silicon carbide is made up of two types: green and black. They are both hexagonal crystals and have a specific gravity ranging from 3.20 to 3.25.
Both black silicon carburide and green silica carbide belong to the aSiC. Black silicon carbide has a SiC content of 95% and is more durable than green silicon carbide. It is used primarily for materials that have low tensile strengths, like glass, ceramics or stone. Green silicon carbide has a SiC content of over 97% and is self-sharpening. It is used primarily for the processing of cemented carbide (a titanium alloy), optical glass and titanium alloy. Also, it can be used to fine grind high-speed steel and for honing and grinding cylinder liners. There is also a cubic silicon-carbide, which is a yellowish-green crystal, prepared through a special procedure. The abrasive tools used to make them are suitable for superfinishing bearings. Surface roughness is processed between Ra320.16microns and Ra0.040.02 microns.
Aside from being an abrasive, silicon carbide can be used in many other ways. This is due to its chemical properties that are stable, such as high thermal conductivity. The powder of silicon carbide can be used to coat a specific impeller, cylinder or other part of a turbine. The inner wall of the refractory can be improved to increase its resistance to abrasion and its life span by upto 2 times. Low-grade Silicon carbide (containing approximately 85% SiC), which is a deoxidizer of excellent quality, can improve the steelmaking process and speed. It also allows for better control over chemical composition. Silicon carbide can also be used to produce silicon carbide for electric heater elements.
It is the second hardest substance in the world, after diamonds (10). It is a good thermal conductor, a semiconductor that can resist oxidation even at high temperatures.
There are at least 70 crystal forms of silicon carbide. Allomorphs of silicon carbide are the most common. It has a hexagonal crystalline structure and is formed above 2000 degC at high temperatures. Below 2000 degC b Silicon Carbide with cubic crystals, similar to diamonds, is formed. The network can be seen on the page. It is eye-catching due to its larger surface area unit than the a catalyst type, even though heterogeneous catalyst support is used. A type of silicon carbide called m-silicon carbide is more stable and makes a nicer sound when it collides. However, until now these two types had not been used commercially.
Due to its high sublimation temp (approximately 27°C) and 3.2g/cm3 specific weight, silicon carbide makes a great raw material for high temperature furnaces or bearings. It does not melt at any pressure, and it has a very low chemical activity. Its high thermal conductivity and breakdown electric field strength as well as its high maximum current densities have led many to try to replace silicon when it comes to high-power semiconductor components. It has a high coupling effect to microwave radiation.
The color of pure silicon carbide, however, is black or brown when produced industrially. This is due to iron impurities. The silica coating on the crystal surface gives it a rainbow-like appearance. To
Pure silicon carbide is a transparent, colorless crystal. The impurities in industrial silicon carbide cause it to be a light yellow or green color, but its transparency can vary depending on the purity. The cubic bSiC is also known as cubic silicon carbide. The different stacking of silicon and carbon atoms creates a variety of a SiC variants. Over 70 types have been identified. bSiC is transformed into aSiC at temperatures above 2100degC. Industrial silicon carbide is produced by refining petroleum coke and high-quality sand in a resistance oven. The silicon carbide blocks that have been refined are crushed and then subjected to acid-base washing, magnetic separation, sieving, or water selection.
It is artificial because silicon carbide has a low natural content. The standard method is to combine quartz sand, coke with silica or petroleum coke. Add salt and wood chips and heat to 2000degC in an electrical furnace.
Its excellent hardness has made it an indispensable abrasive, but its range of applications goes beyond that of general abrasives. Due to its thermal conductivity and high temperature resistance, it is a popular choice for kiln furniture in tunnel kilns. The electrical conductivity of this material makes it a vital electric heating element. SiC smelt pellets (or SiC blocks) are needed to make SiC products. It is not natural garnet, also known as emery. In the industrial production of SiC, quartz, petroleum coal, etc. is usually used. As raw materials, as auxiliary recovery material, or as spent materials. After grinding or other processes, the materials are blended to a charge that has a reasonable particle size and ratio to adjust its gas permeability. An appropriate amount must be added. To prepare green silicon carbide at high temperatures, you need to add the correct amount of sodium chloride. Special silicon carbide electric heaters are used for the thermal equipment to prepare SiC smelting at high temperatures. It consists of a furnace bottom, an end wall with electrodes attached to the inner surface of its surface, a removable sidewall as well as the core body of the electric heater. Both ends of this furnace are electrode-connected. This electric heater uses what is known as buried-powder firing. As soon as you turn it on, the heating begins. The furnace core is at 2500degC (or even higher, between 2660-2700degC). SiC synthesizes at 1450degC (although SiC mainly forms above 1800degC), and co is released. SiC decomposes when the temperature is >=2600. The decomposed si, however, will form SiC and C in the charged.
Each electric heater is equipped with transformers. Even so, during production only one electric heater is operated to adjust voltage according to electrical load characteristics in order to maintain constant electricity. The high-power furnace must be heated for around 24 hours. After an interruption of power, the reaction that generates SiC is complete. After a cooling time, the sidewalls can be removed. The charge is then gradually removed. Silicon carbide can be divided up into many different categories. These are also divided according to their use environment and more often than not, silicon carbide is used in machinery. Silicon carbide seal rings can, for example, be used to seal mechanical seals. These seal rings can be further divided into flat rings, moving bands, static rings and more. Our silicon carbide products can be made in different shapes according to the customer’s requirements. For example, we can produce silicon carbide rings and plates.
One of the silicon-carbide products is silicon carbide, a ceramic with high hardness. It also has high corrosion resistance and high temperature strength.
Silicon carbide ceramics are ideal for seal rings. They have a high level of chemical resistance and wear resistance. The friction coefficient of silicon carbide ceramic is lower when combined with graphite than that of cemented carbide and alumina. Therefore, it can be used to produce PV values of high value, particularly in conditions where strong acids or alkalis are transported. The SIC-1 atmospheric sintered silicon carbide products manufactured by our company are characterized by high density and high hardness. Large production batches can be produced, as well as products of complex shapes. They are suitable to produce high-performance seals. They have exceptionally high PV values. And they’re resistant to strong acids and Alkalis. Our company’s SIC-3 silicon-carbide ceramic works are made from graphite. When combined with other materials, the friction coefficient of silicon carbide is low because it contains fine dispersed graphite particles. It is self-lubricating and therefore ideal for air-tight, dry-friction sealings. It is used to increase the seals’ service life, and improve the reliability of the work.
The furnace charge, after high-temperature calibration, is unreacted (to preserve heat in the furnace), and silicon carbide oxycarbide. (Semi-reactive Material. The main components of the material are C and siO. Binder layer (for bonding Very Tight Material Layer, main elements are C, SiO2, 40-60% SiC and Fe Al Ca Mg Carbonate), amorphous layer (the major component is 70-90 % SiC; it is Cubic SiC b-sic), second-grade SiC (the main ingredient is 90-95% SiC; the coating has formed hexagonal SiC (a coarse SiC crystal), first-class SiC (SiC content is less than 96%, and Unreacted material from the oxycarbide layers and a small part are collected for recycling. Large lumps, tight bonds and impurities such as charges are thrown away. The first-grade material is classified, then coarsely crushed or finely ground, treated chemically, dried, sieved, and magnetically separated into various size black and green SiC particles. It is necessary to go through the water selection process in order to produce silicon carbide.
