Silicon carbide is a kind of refractory material. It is made by refining quartz sand or petroleum coke sawdust through high-temperature smelting. It is a very rare mineral and is relatively rare in nature. Among today's refractory raw materials, this material is still the most widely used in the economy. It is divided into two types in industrial production, namely black and green.

If silicon carbide is black, it basically uses quartz sand and high-quality silica as the main raw materials. Through high-temperature smelting, the mechanical strength is between diamond and corundum, which is sharper and brittle than corundum. If it is green silicon carbide, the main raw material is high-quality silica, but edible salt is added, so after passing a little, the hardness is still between diamond and corundum, but the strength is higher than corundum. This green silicon carbide is usually used in Hawking's tools, and black is mainly used in molded cast iron and non-metallic materials.
Silicon carbide can be successfully developed industrially, so it is not very simple to face this kind of mining. If it is pure color silicon carbide, it is basically a colorless and transparent crystal, and the purity can be seen according to the color. In industrial processing and production, petroleum coke and quartz sand are basically chosen for refining, and through processing, the artificial synthesis can be seen It can be used in many materials, such as monocrystalline silicon, polycrystalline silicon, photovoltaic industry, semiconductor industry, etc., and is processed as a semiconductor material. It can be seen that this high-temperature semiconductor material has a wide range of future applications, and it can not only maximize its role in the photovoltaic field, but this material also plays a role in photovoltaic inverters. After making silicon carbide fiber from silicon carbide, it can become a high-temperature resistant material, and its use effect in the aviation field is still very obvious. It can not only be made into engine blades, but also can be used as a high-temperature material.
