Heavy Calcium Carbonate is one of the most common and widely used mineral compounds in various industries. It is found as a white, water-insoluble powder and is obtained by crushing and grinding natural limestones such as calcite.

Physical and chemical properties of heavy calcium carbonate

Physical state: White powder
Solubility: Insoluble in water.
Density: Typically greater than light calcium carbonate.
Particle size: The particle size in heavy calcium carbonate is larger than its light counterpart.
Specific surface area: It has a lower specific surface area than light calcium carbonate.
Stability: It decomposes into calcium oxide and carbon dioxide at high temperatures.

Applications of heavy calcium carbonate

Plastics industry: It is used as a filler to reduce production costs and improve some physical properties of plastics such as hardness and whiteness.
Paper industry: It is used as a filler and coating to increase the whiteness, smoothness and printability of paper.
Paint and coating industry: It is used as a filler and bleach in various paints and coatings.
Construction industry: It is used as a filler in the production of cement, concrete and other building materials.
Food industry: Used as a calcium supplement in food and medicine.
Agricultural industry: Used as a soil conditioner and fertilizer.
