Carborundum, also known as silicon carbide, is a crystalline solid. It has a crystal structure similar to that of diamond and has high thermal conductivity and hardness.
It is a pseudo latin phrase (usually "nil bastardum carborundum" - but probably more correctly "illegitimi nil carborundum"?) meaning - don't let the bastards grind you down...

It's emery.
Carborundum is used as an abrasive material in applications such as grinding, cutting, and polishing. It is also used in manufacturing processes where high hardness and wear resistance are required, such as in the production of ceramics and refractory materials. Additionally, carborundum is used in the production of semiconductors and as an abrasive in sandpaper and grinding wheels.
Steels are commonly used, but I have a set of different carborundum stones on handles which are much more efficient.

A silicon carbide quandary -- a carborundum conundrum
Illegitimi non carborundum is nonsense. It pretends to mean "Don't let the bastards wear you down." Mixing up fake Latin from English words for comic effect is called "macaronics."
This compound is the silicon carbide, SiC.
