Product Description: Calcium carbonate is an inorganic compound with the chemical formula CaCO₃. It is the main component of limestone, marble, and other minerals. Calcium carbonate typically appears as a white crystal, is odorless, practically insoluble in water, and readily reacts with acids to release carbon dioxide.

Classification:

-Based on production methods: Heavy calcium carbonate, light calcium carbonate, colloidal calcium carbonate, and crystalline calcium carbonate.

- Based on particle size (d):

- Micron-sized calcium carbonate (d > 5μm)

- Fine calcium carbonate (1-5μm)

- Ultrafine calcium carbonate (0.1-1μm)

- Superfine calcium carbonate (0.02-0.1μm)

- Ultramicro calcium carbonate (d≤0.02μm)

Common Particle Sizes: 325 mesh, 400 mesh, 600 mesh, 800 mesh, 1250 mesh, 1500 mesh, 2000 mesh, 2500 mesh, 3000 mesh, etc.

Applications: Widely used in papermaking, metallurgy, glass manufacturing, alkali production, rubber, pharmaceuticals, pigments, organic chemicals, and more.
