Calcium carbonate CAS#471-34-1

Basic Information

Calcium carbonate
powdered; precipitated grades

Calcium carbonate is a mineral raw material associated with limestone, marble and chalk. It is nearly insoluble in water and alcohol and is supplied in powdered or precipitated forms with differing particle characteristics. Applications include cement, mortar, glass and lime manufacture, along with filler use in paper, paints, plastics, adhesives and sealants. Selected grades also serve formulation roles in cosmetics and food products.

product description

Versatile Natural Mineral Resource:Derived from limestone, marble, chalk, and coral, calcium carbonate is one of the most widely used raw materials in the chemical and building industries.


Essential Building Material Ingredient:Widely applied in the production of cement, mortar, plaster, refractories, and glass, supporting major construction applications.


High-Purity Precipitated Grades Available:Offered as both powdered and precipitated calcium carbonate, with precipitated types providing finer particles, higher purity, and uniform particle size.


Broad Industrial Applications:Used extensively in paper, textiles, paints, plastics, adhesives, sealants, and cosmetics for performance enhancement and quality improvement.


Products Description of Calcium carbonate CAS#471-34-1

Calcium carbonate, a natural mineral found in limestone, marble, chalk and coral, is a versatile industrial raw material. It is used in construction (cement, glass), calcium compound production, and as powdered/precipitated grades in paper, paints, plastics, adhesives and cosmetics.


Product Applications of Calcium carbonate CAS#471-34-1

Calcium carbonate (limestone) is the calcium salt of carbonic acid, available in various particle sizes. Nearly insoluble in water/alcohol (pH 9–9.5), it is used as an anti-caking agent, dough strengthener, calcium fortifier and antacid neutralizer, and is the primary raw material for lime production.
