Silicon carbide bricks

Silicon carbide brick is a high-tech silicon carbide raw material produced by mixing high-purity silicon carbide coarse powder and high-active silicon carbide fine powder, grouting and forming at a high temperature of 2450under vacuum pump calcination to make it hardened. Because its raw materials have high purity (SIC99.5%) without a positive intermediate fusion phase, it has high-quality high-temperature physical properties, and the application temperature reaches 1700°C. Recrystallized silicon carbide raw materials are suitable as kiln furniture and kiln parts in the manufacturing industries of porcelain, refractory insulation materials, electronic devices and other manufacturing industries. Its obvious characteristics are its specification reliability and high temperature bearing capacity, and it has excellent environmental protection and energy saving. actual effect.

 

Silicon carbide bricks should use silicon carbide (sic) as the key raw material, and be equipped with various fusing agents according to regulations. After high pressure forming, the refractory silicon carbide brick crafts have excellent heat resistance and high heat transfer coefficient, and With good corrosion resistance, it is an ideal energy-saving insulation material for industrial kilns.

 

Silicon carbide brick refers to an insulation brick with silicon carbide as the main crystal phase made by using silicon carbide as the key raw material. Silicon carbide brick has the advantages of high-quality alkali resistance, acid resistance, abrasion resistance, high compressive strength, high thermal shock resistance, low linear expansion coefficient, and good heat transfer. Its defect is poor oxidation resistance at high temperatures. , The price is relatively expensive.

 

Silicon carbide bricks have high thermal conductivity, excellent wear resistance, thermal shock resistance, and adhesion resistance. It can be used for aluminum electrolysis cell lining, melting aluminum hose and porcelain kiln furniture, large, medium and small ironmaking blast furnace bottom, furnace waist and belly, aluminum refining furnace charge, zinc distillation tank lining, etc.
