General Introduction
Heavy calcium carbonate, also called ground calcium carbonate, is produced by natural superior calcite, which has high purity and whiteness. Heavy (Ground) Calcium Carbonate is widely used as filler and improver in plastic, paint, paper-making, rubber, pharmacy, feed, daily chemical, ceramics, adhesives and ink industry. With the increasing consumption needs, our company is concentrated in calcium carbonate powder processing and exporting as always. The calcite that we used are from our own mines, and we can provide the different standard products to satisfy our customers' requirements.
Structure
The thermodynamically stable form of CaCO3 under normal conditions is hexagonal β-CaCO3, (the mineral calcite).Other forms can be prepared, the denser,(2.83 g/cc) orthorhombic λ-CaCO3 ( the mineral aragonite) and μ-CaCO3, occurring as the mineral vaterite.The aragonite form can be prepared by precipitation at temperatures above 85 °C, the vaterite form can be prepared by precipitation at 60 °C. Calcite contains calcium atoms coordinated by 6 oxygen atoms, in aragonite they are coordinated by 9 oxygen atoms.The vaterite structure is not fully understood.Magnesium carbonate MgCO3 has the calcite structure, whereas strontium and barium carbonate (SrCO3 and BaCO3) adopt the aragonite structure, reflecting their larger ionic radii.
Uses
Industrial applications
The main use of calcium carbonate is in the construction industry, either as a building material or limestone aggregate for roadbuilding or as an ingredient of cement or as the starting material for the preparation of builder's lime by burning in a kiln. However, due to weathering mainly caused by acid rain, calcium carbonate (in limestone form) is no longer used for building purposes on its own, and only as a raw/primary substance for building materials.
Health and dietary applications
Calcium carbonate is widely used medicinally as an inexpensive dietary calcium supplement or gastric antacid.It may be used as a phosphate binder for the treatment of hyperphosphatemia (primarily in patients with chronic renal failure). It is also used in the pharmaceutical industry as an inert filler for tablets and other pharmaceuticals.
Calcium carbonate is used in the production of toothpaste and has seen a resurgence as a food preservative and color retainer, when used in or with products such as organic apples or food.
