The US company Raytheon produced industrial-scale pyrolytic graphite products in 1956, which were successfully applied to the aerospace industry. Compared with ordinary graphite crucibles (made from natural flake graphite as the main raw material and plastic refractory clay or carbon as the binder), pyrolytic graphite crucibles are made from a new type of carbon material - pyrolytic graphite.

The properties of silicon carbide ceramic are very similar to diamonds - it is one of the lightest, hardest and strongest technical ceramic materials, with excellent thermal conductivity, acid resistance and low thermal expansibility. When physical wear is an important factor, silicon carbide is a good material because it has good corrosion resistance and abrasion resistance, which can be used in various applications, such as nozzle, shotgun nozzle and cyclone component.

Silicon carbide (SiC) ceramic honeycomb not only has excellent room temperature mechanical properties, such as high bending strength, excellent oxidation resistance, good corrosion resistance, high wear resistance, and low friction coefficient, but also has the best high-temperature mechanical properties (strength, creep resistance, etc.) among known ceramic materials.

Silicon carbide ceramic is an ideal material for manufacturing sealing rings. When it is combined with graphite material, its friction coefficient is smaller than that of alumina ceramic and cemented carbide, and its self-lubrication performance is good. Therefore, it can improve the sealing ring’s lifetime and working reliability, especially in the situation of acid and alkali transportation.

Al2O3 ceramics have a wide range of usages. Different purity of Al2O3 means different properties, which result in the different uses.
