It’s also used in medicine to produce plaster casts to keep broken bones immobilized while they recover, however many current orthopedic casts are compose...
The chemical formula of Plaster of Paris is CaSO4.1/2H2O known as Calcium Sulphate Hemihydrate. Plaster of Paris is a chemical compound in which an atom of calcium is bonded with a combination of an atom of Sulphur along with four atoms of oxygen to form Sulphate. It is then bonded with two molecules of water to form Calcium Sulphate Dihydrate. Hen...
Plaster of Paris is primarily of three types, that are widely used, 1. Gypsum Plaster – Gypsum plaster, also referred to as Plaster of Paris, is made by heating gypsum to a temperature of 300 °F. Additionally, Anhydrite is produced when gypsum is heated over 392 °F. Dry gypsum plaster powder or Anhydrite transforms into gypsum when combined with wa...

What is Plaster of Paris (POP)?
Plaster of Paris, commonly abbreviated as POP, is a white powdery substance derived from gypsum, a rocklike mineral. When gypsum is heated to about 160-170°C, it loses water and transforms into the hemihydrate form known as POP.
plaster of paris, quick-setting gypsum plaster consisting of a fine white powder (calcium sulfate hemihydrate), which hardens when moistened and allowed to dry. Known since ancient times, plaster of paris is so called because of its preparation from the abundant gypsum found near Paris.

The chemical compound known as Plaster of Paris is Calcium Sulphate Hemihydrate, represented by the formula CaSO4.1/2H2O. It comprises calcium, sulfur, oxygen, and water molecules. In its structure, a calcium atom bonds with a combination of a sulfur atom and four oxygen atoms, forming sulfate.
Plaster of Paris’s chemical name is calcium sulphate hemihydrate and it is chemically a hydrated salt. Plaster of Paris’s formula is CaSO4 ⋅ (1/2) H2O. This means that, on average, one molecule of calcium sulphate has half a molecule of water, as the water of crystallization. Index. Preparation of Plaster of Paris. Reaction With Water.
