i'm not exactly use what you're asking, but if you're asking what chalk powder is made of, then i can answer that.
Chalk is made from the mineral Calcite, which has a chemical formula CaCO3 (calcium carbonate). it's a really common mineral, that u find in limestone, shells of organisms like clams or oysters, and numerous other places

It is the powder that you get after erasing something written in chalk.

The typical answer is CaCO3. The funny thing was once I needed a cheap impure source and found that the chalk I bought was largley CaSO4
