200 Mesh Calcium Carbonate (CaCo3)

Calcium carbonate is an inorganic compound with the chemical formula CaCO3, and is the main component of limestone, marble, etc. Calcium carbonate is usually white crystals, odorless, and essentially insoluble in water. It is one of the common substances found on earth within rocks such as aragonite, calcite, chalk, limestone, marble, travertine, etc. It is also a major component of the bones or shells of some animals. Calcium carbonate is also an important building material with a wide range of industrial uses.

Supplementary Notes

1. Nano calcium carbonate: particle size 10–100 nm (0.01–0.1 μm), not marked by mesh size, equivalent mesh size >12500.

2. The data in the table is the standard reference value of median diameter D50; actual powder has a particle size distribution range depending on manufacturers.

3. Heavy calcium carbonate & light calcium carbonate share the same mesh-particle size standard, differing only in oil absorption value and whiteness.
