Silicon carbide brick

1. The main content of silicon carbide brick is SiC, the content is 72%-99%. Silicon carbide bricks are used in different industries and thermal equipment due to different combinations. According to different bonding methods, silicon carbide brick manufacturers are divided into clay bonding, Sialon bonding, alumina bonding, self bonding, high aluminum bonding, silicon nitride bonding, and so on. What are the uses of silicon carbide bricks? What are the main applications?

2. Because the raw material of silicon carbide brick is silicon carbide, silicon carbide, also known as emery, is made by high-temperature smelting of raw materials such as quartz sand, coke, and wood chips. Silicon carbide is often used to make advanced refractories due to its stable chemical properties, high thermal conductivity, low thermal expansion coefficient, and good wear resistance.

3. Silicon carbide bricks are processed into high-temperature smelting furnace linings using the characteristics of silicon carbide such as corrosion resistance, high temperature resistance, high strength, good thermal conductivity, and impact resistance, and are used in a variety of high-temperature thermal equipment.

4. Silicon carbide products use silicon carbide as raw material, add clay, silicon oxide and other binders to sinter at 1350 to 1400°C. Silicon carbide and silicon powder can also be made into silicon nitride-silicon carbide products in a nitrogen atmosphere in an electric furnace. Carbon products have very low thermal expansion coefficient, high thermal conductivity, good thermal shock resistance, and high high temperature strength. It does not soften after long-term use at high temperature, is not corroded by any acid and alkali, has good salt resistance, and is not wetted by metals and slag. It is light in weight and is a high-quality high-temperature resistant material. The disadvantage is that it is easy to oxidize at high temperature and is not suitable for use in an oxidizing atmosphere. Carbon products are widely used in high-temperature furnace linings (furnace bottom, hearth, lower part of the furnace shaft, etc.), as well as the lining of non-ferrous metal smelting furnaces.
