- Supplier Information
Calcite is a high purity mineral of limestone family. The particle structure is spherical and microcrystalline. It occurs in rhombohedral form and contains very high CaCo3 percentage having low specific gravity. Quality Aspect We are specialized in production of white calcite powder with high carbonate value. Our calcite is of superior grade and well accepted by the industry. Application more...
- Vinayaka Microns
Our range of processed calcite powder is most commonly used in paint as an extender for titanium dioxide, or TiO2. The small and narrowly distributed calcite powder particles help space the individual TiO2 particles and maximize their hiding power. This extension of the prime white pigment can improve opacity and reduce cost.

Calcite Powder / Natural Calcium Carbonate
Micronise & 300 To 500 Mesh Size
Calcite is a natural calcium carbonate with extremely high whiteness, purity and free flowing in nature. It is widely used in Thermoplastic application because of its compatibility with polymers and other organic additives.
It acts as a spacing extender, increasing efficiency of pigment TiO2.
Calcite is also of bio-organic origin but more compacted than Chalk. Best quality calcite is found in Rajasthan.

We manufacture and distribute pure calcite coarse. Calcite is also known as chalk powder or chemically calcium carbonate. This is one of the most widely used minerals available in the earth’s surface. Calcite is found in abundant in sedimentary rocks such as limestone, in metamorphic marble and as a deposit in hot springs. It is also present in caverns as stalactites and stalagmites. Some of the salient features of our calcite coarse include the following:
• Chemical formula: CaCO3
• Color: bright white
• Crystalline structure
Specifications:
Chemical Analysis:
• CaCO3: 95% - 98%
• R2O3: 0.50% max –
• SiO2: 1.5% max
• S: 0.05% max
• P: 0.02% max
Sieve Analysis:
•-52 mesh: 100% passing
•-100 mesh: 25 TO 45% passing- Paradise Minerals
Our process Calcite powder is widely used by Master Batch manufacturer, we provide perfect micron size (d97), to give them best result while processing and give better end product of master batch.

We offer calcite powder, which provide a greater covering strength, thus increasing the performance of high quality paints, oil synthetic and other coatings. The excellent whiteness of our carbonates avoid interference with the paint’s colors and contribute to their opacity and that the paint will cover, without dripping, the surfaces.

Our calcite powder is widely used in plastics as a filler due to its high dispersibility, low oil absorption, high impact resistance, smooth surface finish, easy processing and excellent dimensional stability. They are indispensable for delustration of naturally transparent man-made fibers for instance and guarantee high color intensities and whiteness in plastic components.

Calcite powder offered by us are widely used as mineral fillers in order to obtain a high humidity retention, to improve the consistency and dryness of the final mass. Furthermore, they do not alter neither the physical nor the chemical properties of soap products, nor the viscosity of the mix. They help to improve the cleaning action of soaps and detergents due to an adequate grade of abrasiveness. It is not retained by the textile fibers since they do not contain silica in a free stage and hence not cause damage to the fabrics.. They are also used as secondary pigments.

Calcite is a carbonate of lime, that is abundantly distributed on the surface of the earth. It is mostly found in sedimentary rocks, lime stone in particular. It is also found in metamorphic marble. Calcite is often the primary constituent of the shells of marine organisms, e.g., plankton (such as coccoliths and plank tic foraminifera), the hard parts of red algae, some sponges etc. It is largely used in industries such as: more...
