Properties and Application Fields of Silicon Carbide

Silicon carbide (SiC), which is made from quartz, petroleum coke and wood chips by high temperature smelting within a resistance oven, is also called quartz sand. While silicon carbide is found naturally, it is rare. Moissanite contains silicon carbide as its main component. This non-oxide, high tech refractory material is more widely utilized than any other.
Abrasive silicon carbide, with its high chemical properties, stable chemical properties, excellent thermal conductivity, low temperature expansion coefficient, and outstanding abrasion resistance has many uses. The unique application of silicon carbide powder onto a turbine wheel, cylinder block or other device is an example. You can make the inner wall stronger and prolong its useful life. Use high-grade refractory to reduce heat and shock. It has small dimensions, is lightweight, can withstand high temperatures, and can be used for energy savings. Silicon carbide low grade (containing approximately 85% SiC), is an excellent antioxidant. It may also be used as a speed-up, chemical composition, or control to enhance the quality and quantity of steel. Additionally, silicon carbide electric heating elements can be extensively used for producing silicon carbide.
You can divide silicon carbide products into several categories depending on their environmental requirements. This is mainly used for more mechanical applications. You can divide the silicon carbide sealing rings into three types: flat ring or static ring. Also, we can make silicon-carbide products in various forms according to customers’ needs. For example, parts made of silicon carbide such as flat rings or plates and silicon carbide rings.
Silicon carbide Ceramics offer high hardness as well as high resistance to corrosion and high heat strength. They are widely utilized.
This sealing ring is made from silicon carbide ceramics. It has excellent chemical resistance, strength, hardness, wear resistance, low friction coefficient and high temperatures. Because it has a lower friction coefficient than alumina ceramics or hard alloys combined, it can be used even in very high PV values.
Four main areas that silicon carbide can be used are functional ceramics as well advanced refractories.
1. Industries that use abrasives
Silicon carbide can also be used as production wheel and sandpaper.
2. The field of high-refractory materials
Silicon carbide exhibits excellent corrosion resistance at high temperatures and good thermal conductivity. For indirect heating, non-ferrous, high-temperature metal melting industry, silicon carbide material could be used. It can be used as a silicon carbide material for: Vertical retort furnace, distillation furnace trays and aluminum electrolysis, lined with copper melt furnace, arc plate, thermocouple protective tube; to produce wear, corrosion and other advanced silica carbide ceramic materials. Also, silicon carbide makes a good material for aircraft runway solar water heaters.
3. Industries chemical
Silicon carbide has the ability to be used as deoxidizer. Additionally, it can be modified with steel cast iron structures. This structure can also help produce silicon tetrachloride. It is the raw material that feeds the silicon industry. SiC can be used as a substitute for carbon and silicon deoxidation. SiC has a better deoxidizer active deoxidizer chemical, longer deoxidation time, lower energy use, more stability. Integrated steel-making will improve steel production to enhance economic efficiency, raise the quality of steel and decrease raw material usage.
4. The field for the non-ferrous and smelting of iron
Silicon carbide offers high resistance to impact, heat conductivity, high temperature and high strength.
5. Steel
Service life can be extended by the use of silicon carbide corrosion resistance. It also resists thermal shock, abrasion and is suitable for large blast furnace lines.
6. Refinement of the metalurgical process
Because of its hardness silicon carbide surpasses diamond in wear resistance, it is the perfect material for wear resistant pipe, impeller and pump chamber. Silicon carbide has an excellent wear resistance, with a life span of between 5 and 20 years for cast iron and rubber. This makes it ideal material to use as a runway liner.
7. Building Materials Industry Pottery Wheel
Silicon carbide is a high-temperature conductor and heat radiation material, used in the manufacture of kiln furniture, which can reduce capacity, loading capacities and improve quality. Also, the manufacturing cycle will be reduced by adding ceramic glaze to the fritting indirect materials.
8. Jewelry
Synthetic Moissanite is sometimes also called synthetic Silicon Carbide. It has the same diamond adamantine sparkle, stronger “fire color”, and is much closer to imitations.
