At present, the gypsum powder on the market is divided into raw gypsum powder and plaster of Paris.
The plaster of Paris (also known as hemihydrate gypsum), divided into α-type gypsum powder and β-type gypsum powder, is formed from gypsum raw materials by heating at a high temperature of 105-200 ℃.
The plaster of Paris is a kind of rigid gelling material. It has two kinds of materials, both are orthorhombic crystals. The physical properties of the two gypsum powders are different.
The α-type gypsum powder has good crystallinity and solidity, so it can be used in ceramic molds, sculptures, gypsum lines and high-end buildings. The β-type gypsum powder is mainly used for mortar levelling, gypsum board production, painting, etc.

Advantages of gypsum powder for construction:
- It has excellent fire resistance. Gypsum board is a non-combustible material with certain fire performance and some can even be used as the fire protection layer of a steel structure.
- It has the characteristics of keeping warm and breathing. It can meet the functional requirements of indoor heat preservation, sound insulation, fire protection, waterproof, flexible separation, etc. It is also a good indoor ornamental material.
- No environmental pollution. The production process of gypsum building materials does not emit waste gas, waste residue, wastewater and substances.
- It can be recycled. The discarded gypsum building materials can be used as raw materials for the production of gypsum building materials after being crushed, screened and calcined, without generating construction waste.
