Silicon Carbide Application

Carborundum, also known as silicon carbide (SiC), is made from quartz sand, petroleum coke (or coal coke), and wood chips (which need to be added with salt when producing green silicon carbide) through high-temperature resistance furnaces. Silicon carbide also exists in nature as a rare mineral, moissanite. Silicon Carbide is also called Carborite. Among contemporary non-oxide high-tech refractory raw materials such as C, N, B, silicon carbide is the most widely used and economical one, which can be called gold steel sand or refractory sand. At present, silicon carbide produced by China's industry is divided into black silicon carbide and green silicon carbide, both of which are hexagonal crystals with a specific gravity of 3.20 to 3.25 and a microhardness of 2840 to 3320 kg / mm2.

The use of silicon carbide in the metallurgical industry:

Non-ferrous metals

The use of silicon carbide has high temperature resistance, high strength, good thermal conductivity, and impact resistance. It is used as a high-temperature indirect heating material, such as a solid tank distillation furnace, rectification furnace tray, aluminum electrolytic tank, copper melting furnace lining, zinc powder furnace arc. Template, thermocouple protection tube, etc.


Utilizing the characteristics of silicon carbide's corrosion resistance, thermal shock resistance, wear resistance, and good thermal conductivity, it is used for large blast furnace linings to improve service life.

Metallurgical beneficiation

Silicon carbide is second only to diamond in hardness and has strong wear resistance. It is an ideal material for wear-resistant pipes, impellers, pump chambers, cyclones, and linings of ore buckets. Its wear resistance is cast iron. The service life of rubber is 5 --20 times & def is also one of the ideal materials for aviation flight runways.

Building Material Ceramic Wheel

Utilizing the characteristics of thermal conductivity, thermal radiation, and high thermal strength, manufacturing thin-plate kiln furniture can not only reduce the capacity of the kiln furniture, but also increase the capacity of the kiln and product quality, shorten the production cycle, and it is a ceramic glaze baking sintering Ideal indirect material.
