Abrasive Grade Silicon Carbide – Uses Of

Silicon Carbide Grit

Silicon Carbide Grit & Powder

The main uses for abrasive grade Silicon Carbides (Carborundum) are:

Due to the very hard structure of silicon carbide (silicon + carbon) , it has historically been used as an abrasive.  Today, there are many high tech uses for varying grades of Silicon Carbide such as electronics, brake pads, ceramics, LED’s, diodes, transistors, semiconductive research, heating elements, even jewelry.  Gone are the days when Silicon Carbide was known only as an abrasive.

How Is It Made?  Silicon carbide is  manufactured by mixing silica sand (SiO2) and finely ground coke (carbon) together, then they are put into a brick lined electric furnace and baked at high temperature, while at the same time, an electric current is passed through a conductor.  This process can take days from start to finish, with the end result being chunks of silicon carbide of varying purity.   The aggregate is then sorted, crushed, and graded.
