Calcium Carbonate

English

Calcium Carbonate

Calcite, also known as Chalk or Natural Calcium Carbonate, which gets its name from "chalix" the Greek word for lime, is a most amazing and yet, most common mineral. It is one of the most stable, common & widely dispersed minerals on the face of the Earth. It forms oolitic, fossiliferous and massive limestones in sedimentary environments and even serves as the cements for many sandstones and shales. Limestone becomes marble from the heat and pressure of metamorphic events. Calcite is even a major component in the igneous rock called carbonatite and forms the major portion of many hydrothermal veins. Some of these rock types are composed of better than 99% calcite. Dogtooth spar, iceland spar, nailhead spar & satin spar are varieties of Calcite.

Calcite is not the only calcium carbonate mineral. There are no less than three minerals or phases of CaCO3. Aragonite and vaterite are polymorphs (latin for "many shapes") with calcite, meaning they all have the same chemistry, but different crystal structures and symmetries. Aragonite is orthorhombic, vaterite is hexagonal and calcite is trigonal. Aragonite is a common mineral, but is vastly out distanced by calcite which is the more stable mineral at most temperatures and pressures and in most environments. Vaterite on the other hand is extremely scarce and rarely seen. Aragonite will over time convert to calcite and calcite pseudomorphs after aragonite are not uncommon.

Chemically Calcite is known as Calcium Carbonate (CaCO3).

Properties / Advantages
High Purity                      - Stable, reproductive properties of end products.
Good Brightness               - Neutral white tone, good hiding effect, consistent color of end product.
Low Moisture Absorption   - Good molded surface, well suited for plastic paints.
Low Iron Content             - Low yellowness index.

Application Scope
Used in emulsion based premier paints, powder coating paints, cement paints, texture coatings, cement primers, wood primers, metal primers and many others.
Used in rigid PVC pipes, footwear, cables and many others.
Used in rubber industry as bulk fillers. Used as glazing material & body constituent in manufacture of ceramic tiles.
Used in variety of construction products, water proofing compounds, etc.

Calcite Powder
Calcite Powder / Natural Calcium Carbonate

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 Turkey.

Chemical Composition Of Calcite
Caco3 99.20 % to 99.60%
Mgo 0,30
Silica 0,10

Advantages of our Calcite
Higher flow properties
Higher mechanical properties in thermoplastic applications.
Better gloss and whiteness in Paints and Powder coating applications.

Applications of Calcite powder

Plastics : Functional Filler and Extender are used in a large range of applications in the plastics industry. They are indispensable for delustration of naturally transparent man-made fibers, for instance, and guarantee high color intensities and whiteness in plastic components.

Application

PP master batches, Automotive and Furniture compounds.
LDPE masterbatches.
Rigid PVC Pipes.
Leather Cloth Industry.
Paints, Inks, Powder Coating and Ceramic Industry.
Rubber Industry.
As a flux in Glass Industry and in sizing of Textile goods.

Coated Calcite Powder:
We also do coating on Calcite powder. We provide coating of Steric Acid. The Coated Calcium Carbonate powder is used in plastic compounds manufacturing to avoid moisture contains.

Grades of Calcite powder are available in, 300 Mesh, 400 Mesh, 500 Mesh BSS standard and in Micronise grades Our grades are available in 13 Microns and Top cut 10 Microns.
