Calcium carbonate is an inorganic compound with the chemical formula CaCO3, generally in the form of white powder or granules. It is solid at room temperature and pressure and insoluble in water, but it will dissolve in acidic solutions and can generate carbon dioxide gas.
VIMATERIAL can produce high-purity CaCO3 powder. If you have any needs, please contact us.
Chemical formula：CaCO3
Molar mass：100.09 g/mol
Appearance：white solid
Density：2.7 – 2.9 g/cm³
Melting point：1339 ℃
Solubility: It is difficult to dissolve in water and insoluble in organic solvents such as alcohols.
Stability: CaCO3 is stable at room temperature and pressure, but it will decompose into calcium oxide and carbon dioxide at 825-896.6℃.
Acidity and alkalinity: CaCO3 reacts with acid to generate corresponding salts and water, showing acidity.
Thermal stability: When heated to a certain temperature, it will decompose to generate calcium oxide and carbon dioxide.
According to the production method: it can be divided into heavy CaCO3, light CaCO3, colloidal CaCO3 and crystalline CaCO3.
According to the average particle size of the powder: it can be divided into micro-calcium carbonate (d>5um), micro-powder calcium carbonate (1~5um), fine calcium carbonate (0.1~1μm), ultrafine calcium carbonate (0.02~0.1μm), and ultrafine calcium carbonate (d≤0.02um).
According to the arrangement of atoms and ions: it can be divided into crystalline calcium carbonate and amorphous calcium carbonate.
1. Rubber industry: It is an important filler that can increase the hardness and strength of rubber products while reducing costs.
2. Plastic industry: It can be used as a reinforcing agent and filler for plastics, which can improve the hardness and impact resistance of plastic products and reduce production costs.
3. Paper industry: It is a whitening agent that can make paper more glossy and white, and can increase the thickness and quality of paper.
4. Building materials industry: It can be used as an additive for building materials such as paints and coatings, which can improve the adhesion and hardness of coatings.
5. Metallurgical industry: It can also be used as a flux and reducing agent in the metallurgical industry.
6. Pharmaceutical industry: CaCO3 can be used in medicine, for example, to treat calcium deficiency.
CaCO3 is a non-toxic substance, and it does not have any radioactivity or corrosiveness. Long-term contact will not have any harmful effects on the human body. In industrial production, calcium carbonate is also widely used and has passed the national standard inspection and can be used safely.
Our products implement the most stringent quality management system. There are strict inspection standards for incoming materials, processes, final inspections, and factory inspections. Strict isolation measures will be adopted for unqualified processing to prevent unqualified products from flowing into the next process.
