What is the raw material of SiC?

SiC Production Process | Washington Mills

Silicon carbide crude is produced by mixing silica (SiO2) with carbon (C) in an electric resistance furnace at hgh temperatures.

What's the zirconia or silicon nitride full ceramic? 

1. White ceramic bearings are made by ZrO2（Zirconium Oxide）

Zirconium Oxide ceramic ball bearing is mainly white.That is a very hard but also very light material. Boasting an excellent resistance to water, saltwater and many acids and alkalis, it also has a very wide temperature range and is suitable for use in high vacuum applications. 

2. Black ceramic bearings are made by Si3N4（Silicon nitride）

The silicon nitride ceramic ball bearing is mainly black. It has high strength, high wear resistance, high temperature resistance, corrosion resistance, acid and alkali resistance, and it has great electrical and magnetic insulation properties. It is one of the hardest materials in the world.
