An Overview of Reaction Bonded Silicon Carbide

Reaction Bonded Silicon Carbide, also called silicolated silicon carbide or silico-silicone carbide, is a kind of carbide which is made by a process between a chemical reaction between graphite or porous carbon and liquid silicone. This type of carbide is different from the normal crystalline forms because the bonds are formed between silicon atoms rather than between carbon atoms. Also, the bonds are much more flexible and can be much tighter than those in crystalline carbides…
