Feiz new works company produce Calcium Carbonate with High Purity and High whiteness with competitive price

Feiz New Works Company owns very rich and pure mines of calcium carbonate. The company’s calcium carbonate purity is more than 98% and its whiteness is more than 98%.

Calcite is the most stable polymorph of calcium carbonate (CaCO3). Other polymorphs of calcium carbonate are the minerals aragonite and vaterite. Aragonite will change to calcite over timescales of days or less at temperatures exceeding 300°C, and vaterite is even less stable


usage of calcium carbonate:

  • calcium carbonate is used in Industrial applications:

Calcium carbonate has many uses in various industries. The main use of calcium carbonate is in the construction industry, either as a building material or limestone aggregate for road building or as an ingredient of cement or as the starting material for the preparation of builder’s lime by burning in a kiln.

Calcium carbonate is also used in the purification of iron from iron ore in a blast furnace.

Calcium carbonate is one of the most used minerals used in the paper industry, plastics, paints and coatings as fillers and coatings (due to its special white color). Because of  high purity and high whiteness of Feiz New Works company’s Calcium Carbonat, it is very suitable for the paper industry. so our company is contracting with international paper making companies.

Calcium carbonate has traditionally been a major component of blackboard chalk.

Calcium carbonate is used in ceramic and tile industries, especially the glazing industry.

  • calcium carbonate is used in Health and dietary applications:

Calcium carbonate is widely used medicinally as an inexpensive dietary calcium supplement for gastric antacid.

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 calcium oxide as well as toothpaste and has seen a resurgence as a food preservative and color retainer, when used in or with products such as organic apples.

  • Agricultural use

is used to correct soil and adjust its pH
