Silicon carbide is a very stable and chemically
inert compound. It is an extremely hard material, with a Mohs hardness rating
of 9, close to that of diamond. It is also characterized by its high thermal
conductivity, high-temperature strength, low thermal expansion, resistance to
chemical reaction, and ability to function as a semiconductor. Its superior
thermal strength and conductivity make Silicon Carbide a favoured material for
linings in reactors and boilers in the chemical industry. Its high
refractoriness also offers greater durability and safety.
