Product Detail

Calcium carbonate (CaCO₃) is an inorganic compound commonly known as greystone, limestone, stone powder, marble, etc. Calcium carbonate is neutral, insoluble in water, soluble in hydrochloric acid. It is one of the common substances on the earth, present in aragonite, calcite, chalk, limestone, marble, travertine and other rocks, and is also the main component of animal bones or shells. Calcium carbonate is also an important building material and is widely used in industry.

1. Industrial field: Calcium carbonate is an important raw material for many industries, such as building materials (cement, lime, artificial stone, etc.), steel purification, glass manufacturing, etc. In the plastics, rubber, coatings, silicone rubber and other industries, calcium carbonate is commonly used as a filler to reduce costs, but also to improve the stability of plastic products, hardness, rigidity, heat resistance and processing properties. It is also used in the production of papermaking, ceramics, sugar and adhesives.

2. Pharmaceutical field: Calcium carbonate also has applications in the pharmaceutical field, such as as a calcium supplement or an antacid.

3. Agriculture: In agriculture, calcium carbonate can be used to neutralize the acidity of soil and improve the soil environment.

4. Other areas: Calcium carbonate can also be used to manufacture ink, adding calcium carbonate to ink can improve its gloss and brightness, reduce costs, and has good printing performance. Adding calcium carbonate to the adhesive can change the properties of the adhesive layer, increase the bonding strength, hardness, heat resistance and so on. In addition, calcium carbonate can also be used to make cosmetics, toothpaste and other daily necessities.
