Ground Calcium Carbonate
Description
Ground Calcium Carbonate (GCC) is a finely ground powder made from naturally occurring calcite ores, like limestone, marble, or chalk. It’s a versatile material used across various industries due to its unique properties. GCC is primarily composed of calcium carbonate (CaCO3) and is produced by grinding and classifying these raw materials to achieve specific particle sizes and purity levels
Typical Properties
High purity: Ground Calcium Carbonate has a high level of purity, which makes it suitable for use in food, pharmaceuticals, and other applications where purity is important.
Fine particle size: GCC has a fine particle size, which makes it easy to mix with other materials and improves its dispersibility.
High brightness: GCC has a high level of brightness, which makes it useful in paper, paint, and other industries where a bright white color is desired.
High whiteness: GCC has a high whiteness level, which makes it an ideal choice for applications where a bright white color is desired.
Chemical stability: GCC has high chemical stability and is resistant to acids, alkalis, and other chemicals.
Low abrasiveness: GCC is not abrasive and does not wear down the machinery or equipment it comes into contact with.
Low oil absorption: GCC has a low oil absorption capacity, which makes it useful in the production of paints, coatings, and other products where oil absorption is a concern.
These are just a few examples of the unique properties of Ground Calcium Carbonate that make it a valuable material in many industries.
Higher flow properties

Variation of the specifications stated due to natural raw materials & environment conditions are possible. though they have no influence on the application properties described.
Applications
Adhesives and Sealants: GCC is used as a filler to improve the properties of adhesives and sealants.
Animal and Pet Feeds: It serves as a calcium supplement and filler in animal and pet food.
Construction: GCC is a component in construction materials like cement, mortar, and concrete.
Fillers and Coatings: It’s widely used as a filler in plastics, rubber, and paper, as well as in paints and coatings to improve opacity and brightness.
Glass and Ceramics: GCC is used as a raw material in the production of glass and ceramics.
Paper Industry: It acts as a filler and coating pigment in paper manufacturing.
Plastics: GCC is used as a filler to modify the properties of plastic products.
Rubber and Elastomers: It enhances the properties of rubber and elastomer products.
