Hemihydrate

In chemistry, a hemihydrate (or semihydrate) is a hydrate whose solid contains one molecule of water of crystallization per two other molecules, or per two unit cells. This is sometimes characterized as a solid that has one "half molecule" of water per unit cell.^[1] An example of this is calcium sulfate hemihydrate (CaSO₄·0.5H₂O or 2CaSO₄·H₂O), which is the hemihydrate of calcium sulfate (CaSO₄).
