The Introduction of Silicon Carbide Brick

Sintered Silica Refractories

Silicon carbide brick is a kind of refractories and takes Silicon as the main raw material. The content of silicon carbide is from 72% to 99%. Generally, It takes the black silicon carbide with a Silicon content above 96% as the raw material, adding some binder aid, then these materials are mixed together and sintering in high temperature.

It is a kind of high performance refractory with characteristics of good corrosion and wear resistance, high good thermal shock stability, high thermal conductivity, and low thermal expansion coefficient. Therefore, silicon carbide bricks are widely used in various industry.

We are one of the earliest deep processing enterprises in China that takes silicon carbide as raw material. As a manufacturer of specially produce high-quality silicon carbide brick, we possess advanced research and development and engineering technology teams, strictly control the material ratio, meet clients needs and ensure product quality. We have provided a large number of high-quality and energy-saving silicon carbide products for many domestic and foreign clients. We are amply trusted and highly praised by customers at home and abroad.

The Introduction of Silicon Carbide Brick

Good Heat Conductivity

The thermal conductivity of silicon carbide bricks is the highest among refractory materials, generally greater than 18. It is widely used in many industry fields such as the cooling walls and heat exchangers of blast furnace.

Excellent Erosion Resisting

Silicon carbide brick is a kind of neutral refractory material, so the corrosion resistance to acidic and alkaline solutions is excellent, it is applied to various industries such as steel, non-ferrous metals, glass, chemical, etc.

Excellent Abrasive Resistance

The raw materials of silicon carbide brick is a kind of high-quality abrasives, so the wear resistance is also excellent, it is uaually used for the circulating fluidized bed boilers in thermal power station and the water flushing slag tanks in iron and steelworks.

Good Thermal Stability

The resistance of silicon carbide brick to rapid heat and cold is very obvious, so the thermal stability of silicon carbide bricks is also very good, it is usually used for the nozzle area of the kiln.
