The advantages of silicon carbide refractory castable lie in its high heat conduction, low thermal expansion, and no reaction with slag. It has been used as slag reaction and high temperature peeling kiln site for a long time.
The disadvantage of silicon carbide refractory is that the chemical properties are very unstable under certain atmosphere.In oxidation gases such as oxygen, water vapor, carbon monoxide, carbon dioxide) easy to corrode, iron oxide, etc, are easy to be in the hot metal and vacuum oxidation decomposition, the downside is that the refractory castable with carborundum dissolved water, in water system such as castable monolithic refractories, sometimes illiquid caused the density of silicon carbide refractory castable is bad, the third weakness is lack of sintering, hard to get high strength, but sometimes it is difficult to produce sintering and contraction, in monolithic refractories is a virtue.

Black silicon carbide description Black silicon carbide is produced at high temperature in an electric resistancetype furnace with quarts and petroleum as its main raw materials. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused fused alumina. It is brittle and sharp and has electrical and heat conductivity in some degree. The abrasives made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc. It is also broadly used as refractory material and metallurgical additive.
