The properties and uses
of calcium sulfate in the field of chemical production raw materials
1. the properties of calcium sulfate

calcium sulfate (CaSO4) is a common inorganic salt with a variety of properties. It usually exists in the form of white powder or crystal, which has high chemical and thermal stability. The solubility of calcium sulfate increases with the increase of temperature, but the solubility is low at room temperature. In addition, calcium sulfate also has good acid resistance, alkali resistance and water resistance.

2. the use of calcium sulfate

1. building materials
calcium sulfate in the field of building materials are widely used, mainly used as gypsum board, gypsum block, plastering gypsum and other building products raw materials. These products have good heat insulation, sound absorption and fire resistance, so they are widely welcomed in the construction industry.
2. Chemical raw material
Calcium sulfate can be used as a raw material for many chemical products, such as for the production of sulfuric acid, phosphate fertilizer, citric acid, etc. In addition, calcium sulfate can also be used to prepare various calcium compounds, such as calcium carbonate, calcium hydroxide, etc.
3. medical use
calcium sulfate is also widely used in the medical field, mainly used as bone graft material in orthopedic surgery. Because of its good biocompatibility and bioactivity, it can promote bone regeneration, so it plays an important role in orthopedic surgery.
4. Food additive
calcium sulfate can be used as a food additive to adjust the taste and texture of food. It is often added to soy products, dairy products, bread and other foods to improve the taste and quality of food.

In conclusion, calcium sulfate has a wide range of applications in the field of chemical production raw materials, mainly due to its unique properties and diverse uses. With the continuous progress of science and technology, the application field of calcium sulfate will continue to expand.
