When it comes to silicon carbide, many people may still be limited to abrasive this piece, in fact, the rapid development of the economy in recent years, silicon carbide has gradually seized the market of emerging industries. People who understand silicon carbide may know silicon carbide ceramics, so what are the uses of silicon carbide ceramics?
Silicon carbide material as a new material has been widely used, more and more used in the production of silicon carbide ceramics, this is why? Let's take a look
The advantages of silicon carbide ceramic products
1, reusable, will not cause material waste, advocate sustainable development;
2, chemical corrosion resistance, can be used in high-corrosion chemical plants;
3, high temperature resistance, 1800℃ normal use, and will not be melted damage, strong stability;
4, resistance to sudden cooling and sudden heat, not easy to burst, strong stability;
5, high thermal conductivity, high temperature stability, stable structural performance.
The advantages of silicon carbide ceramics also make it a good ceramic material, which is widely used in metallurgical, chemical, energy and other industries, so let's take a look
The use of silicon carbide ceramics
1, the application of heating elements
The important electrical conductivity of silicon carbide makes it a raw material for the manufacture of lOOO. Silicon carbide heating element is an important product of silicon carbide material and has a broad market.
2, metallurgy, chemical application
From the 1970s to the early 1990s, silicon carbide materials have high resistance to hot metal, slag and alkali metal corrosion, and have high thermal conductivity and wear resistance. 65 large blast furnaces in the world use silicon nitride combined with silicon carbide material as furnace body material, which extends the smelting time of aluminum, copper and zinc in blast furnace life to 20. Various SIC materials are also widely used as furnace linings or crucible. In the chemical and metallurgical industries, ceramic heat exchangers are often used to preheat various gases or liquids in order to make full use of the heat in the exhaust gas of various hot furnaces.
3. Application of energy and environmental protection
Direct purification of gas at high temperature can use the sensible heat of gas in the heat exchanger, which can greatly improve the thermal efficiency compared with normal temperature purification. The direct application of high temperature purified gas to gas turbine power generation can greatly improve the power supply efficiency, reduce the emission of harmful substances, and save water.
The above is to introduce the use of silicon carbide ceramics, because of the excellent and benign silicon carbide ceramics, but also more and more used in industry and new industries. Hope you can be helpful to everyone!
