Products Description
What is Calcium Carbonate CAS 471-34-1?
Physical and Chemical Properties
Appearance: It is a white solid, usually in the form of powder or lump.
Density: Approximately 2.7 - 2.95g/cm^3
Melting point: 825°C (Under standard atmospheric pressure, it decomposes into calcium oxide and carbon dioxide when the temperature exceeds this value.)
Solubility: It is insoluble in water, with a very low solubility in water. However, it can dissolve in dilute acids such as hydrochloric acid and nitric acid, generating carbon dioxide gas at the same time.
Applications：
1.Construction Industry: Calcium carbonate is widely used in the production of cement, concrete, and mortar. It is also used as a filler in building materials.
2.Paper Industry: Used as a filler and coating pigment.
3.Paint and Coating Industry: Used as a pigment and filler to improve the hiding power, durability, and weather resistance of paints and coatings.
4.Food Industry: Calcium carbonate is used as a food additive, mainly as a calcium supplement, anti - caking agent, and pH regulator. It is commonly added to products such as flour, bread, and dairy products.
5.Pharmaceutical Industry: Used as a calcium supplement in tablets and capsules. It is also used as an excipient in some medications.
6.Agriculture: Applied to soil to adjust the pH and provide calcium to plants.
