Description:

Calcite powder is a finely ground, white or colourless crystalline powder composed of calcium carbonate (CaCO3). It is a common form of natural calcium carbonate and is derived from limestone, marble, or chalk. Calcite powder is known for its versatility and wide range of industrial applications.

Colour:

Calcite powder is typically white, colourless, or has a light tint, but it can sometimes exhibit various colours due to impurities or mineral inclusions.

Uses:

• Manufacturing: Calcite powder is used in the manufacturing of various products, including paints, plastics, rubber, ceramics, and paper, to enhance their properties.
• Construction: In the construction industry, it is used as a filler in the production of concrete and mortar, improving their strength and workability.
• Agriculture: Calcite powder is applied in agriculture as a soil conditioner to neutralize acidic soils and provide essential calcium to plants.
• Pharmaceuticals: In pharmaceuticals, it is used as a filler in tablets and capsules and as a calcium supplement.
• Food and Beverages: It is used as a food additive (E170) in the form of calcium carbonate to regulate acidity and provide calcium fortification in food products.

Properties:

• Chemical Formula: CaCO3
• Hardness: 3 on the Mohs scale (relatively soft)
• Transparency: Usually opaque when in powder form
• Lustre: Dull to earthy
• Specific Gravity: 2.71
• Crystal System: Trigonal

Calcite powder is valued for its high calcium content and is an essential component in various industries, contributing to the improvement of product quality and performance. Its fine, powdery texture makes it easily mixable and adaptable for numerous applications.
