Calcium Sulfate Dihydrate → Calcium Sulfate, Hemihydrate

Participants

Reaction Steps

This chemical reaction indicates that calcium sulfate dihydrate plus heat yields calcium sulfate hemihydrate plus water vapor. This process is conducted in a "calciner," several types of which are known in the art (e.g., a calcidyne calciner). A flash calcination impact mill is an apparatus for simultaneously drying, grinding, and calcining gypsum.
