The use of reaction sintered silicon carbide ceramic has high temperature resistance, high strength, good thermal conductivity, and impact resistance.RBSIC material is used as a high-temperature indirect heating material. Reaction bonded Silicon carbide are widely used in metallurgical high-temperature materials, such as reaction sintered silicon carbide retorts, reaction bonded Silicon carbide distillation furnace trays, RBSIC aluminum electrolysis tanks, reaction bonded silicon carbide ceramic copper carbonization furnace lining, arc shaped plates for zinc powder furnaces, RBSIC thermocouple protection tubes, etc.

The use of reaction bonded silicon carbide ceramic is very widely, currently mainly used as abrasive and refractory materials, which account for the majority of silicon carbide production.

Silicon carbide ceramic material has excellent properties such as high temperature mechanical strength, high hardness, oxidation resistance, radiation resistance, corrosion resistance, thermal stability, small thermal expansion coefficient, and good chemical corrosion resistance. It has been widely used in many fields such as industrial machinery, national defense semiconductors, environmental protection, nuclear energy, etc.

The specific preparation process of reaction sintered silicon carbide for casting mainly includes steps such as raw material preparation, molding, drying, and sintering.

The preparation process of reaction bonded silicon carbide ceamic is relatively simple.One is when the temperature reaches the melting temperature of silicon, producing the liquid phase of silicon.

The high hardness and low friction coefficient of sintered silicon carbide give it excellent wear resistance, especially suitable for various sliding friction and wear conditions. Sintered Silicon carbide has a very high temperature strength, the bending strength at 1400 ° C is the same as the bending strength at room temperature, can be processed into a variety of shapes, dimensional accuracy and high surface finish of the sealing ring, with good air tightness and long life characteristics, so Sintered silicon carbide can be used for mechanical sealing under high temperature conditions.

Refractory Si3N4 crucible is made of high purity silicon nitride powder after the traditional mixture granulation process treatment and then put into the high temperature of about 1650℃ -1900℃.

High wear resistance Si3N4 ceramics has many advantages than that metal materials and polymer materials do not have

Recently, the American advanced ceramic company BlaschIntroduces launched a new type of oxide combined with silicon carbide industrial ceramics. According to the introduction, Oxide bonded silicon carbide Sagger is specially developed for heat resistance, corrosion resistance and wear resistance requirements, and has excellent non-wettability, suitable for non-ferrous metal metallurgical applications.

High Temperature Boron nitride parts with white properties as graphite has been desired for many years. This material is called "white graphite". As an advanced ceramic material with excellent performance, its application and new synthesis method have become a hot spot and frontier problem in the field of material research.
