Introduction to silicon carbide products
Silicon carburide also known by the names moissanite or emery is an inorganic material 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 to make green silicon carbide). In nature, silicon carbide is found in the rare mineral moissanite. It is the most popular and cost-effective refractory material among the non-oxide materials like C, N, and B. It can also be called refractory or gold steel. 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 for honing and fine grinding tools made from high-speed steel and for 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 of 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 stability, high thermal conductivity (low thermal expansion coefficient), and wear resistance. 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 an excellent deoxidizer and can accelerate steelmaking, improve steel quality and allow for better control of 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 a diamond, is produced. The network can be seen on the page. It is attractive because the unit surface is higher than that of the a type. 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 bearings and high-temperature ovens. 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. Besides having a strong microwave coupling, its high sublimation temperatures make it a practical material for heating metals.
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 surface of the crystal 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 light yellow or green. It can also be blue, black, or dark brown. Its clarity varies according to its purity. The cubic b-SiC 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 then crushed and subjected to acid-base washing, magnetic separation, sieving, or water selection in order to obtain products with different particle sizes.
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 is made by melting SiC blocks, or pellets. Because they are hard and contain C, SiC pellets used to be called emery. 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. They must be blended after grinding or other processes to obtain a charge that has a good ratio and suitable particle size for adjusting the gas permeability of the charge. 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. Its main components are the bottom of furnace, end wall with electrodes inside, removable sidewalls and furnace core body. Both ends 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 (but 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 power. 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 categorized into different types of products. These are grouped according to their use environment and tend to be more 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 special shaped parts, plates and rings.
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, a high degree of strength, elasticity, hardness 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. Our company’s SIC-1 silicon carbid atmospheric sintered product line has high density and high hardness. It also produces large batches of products, and can produce products with complex shapes. These products are designed for sealing applications requiring high performance, with high PV values. They also resist strong acids and Alkalis. Our company’s SIC-3 silicon-carbide ceramics are made from graphite containing silicon carbide. When combined with other materials, the friction coefficient of silicon carbide is low because it contains fine dispersed graphite particles. It has excellent self-lubricating qualities, making it 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 is composed of unreacted material for heat preservation, silicon carbide and oxycarbide. The binder layer is used to bond the very tight material. It is composed of C, SiO2, Fe, Al Ca Mg Carbonate, 60% to 70% SiC. The unreacted and a small part of the material of the layer of oxycarbide are collected and used as waste. The remaining material of the layer of oxycarbide is collected along with the amorphous, second-grade, and recycled materials. Large lumps, tight bonds and impurities such as charges are discarded. First-grade product is classified and then coarsely or finely crushed. It’s then chemically processed, dried, sieved, and magnetized into various size black and green SiC particles. It is necessary to go through the water selection process in order to produce silicon carbide.
