What Is Calcite Powder?

Calcite powder is a finely milled crystalline substance composed of calcium carbonate (CaCO₃). It generally appears white or colourless and represents one of the most common natural forms of calcium carbonate. This powder is derived from natural sources such as limestone, marble, and chalk and is widely used due to its versatility and broad industrial relevance.

Colour Characteristics

Calcite powder is typically white or colourless. In some cases, minor colour variations may occur due to natural impurities or mineral inclusions present in the raw material.

Industrial Applications of Calcite Powder

1. Manufacturing Industry

Calcite powder is extensively used in the production of paints, plastics, rubber, ceramics, and paper, where it enhances product performance and overall quality.

2. Construction Sector

In construction, calcite powder is used as a filler in concrete and mortar to improve strength, durability, and workability.

3. Agricultural Use

Calcite powder is applied as a soil conditioner to neutralize acidic soils and provide essential calcium for healthy plant growth.

4. Pharmaceutical Industry

In pharmaceuticals, calcite powder is commonly used as a filler in tablets and capsules and also functions as a calcium supplement.

5. Food & Beverage Industry

Calcite powder is used as a food additive (E170) in the form of calcium carbonate to regulate acidity and provide calcium fortification in various food products.
