Gypsum | Mineral - Hosokawa Micron Powder Systems

Gypsum is a mineral composed of calcium sulfate dihydrate (CaSO4-2xH20), which is formed when a lake or sea has evaporated. The gypsum is then mined from the evaporated beds. Another way gypsum is formed is during the flue gas desulfurization process in power stations. Gypsum is used in construction, especially in sheet-rock and wall finishing.

What is Gypsum Ceiling? | Hunker

Gypsum does not absorb sound very well, so other types of material may be preferable if soundproofing is a concern. Also, gypsum products are very susceptible to water damage. For areas that have high moisture content, such as bathrooms or dank basements, you will need to use a chemically treated gypsum wallboard that is moisture resistant.
