The main classification of calcium carbonate powder

According to the different production methods of calcium carbonate, calcium carbonate can be divided into heavy calcium carbonate, light calcium carbonate, colloidal calcium carbonate and crystalline calcium carbonate. According to the average particle size (d) of calcium carbonate powder, calcium carbonate can be divided into particulate calcium carbonate (d>5μm), micropowder calcium carbonate (1μm), and ultrafine calcium carbonate (0.02μm). Calcium carbonate can be divided into crystalline calcium carbonate and amorphous calcium carbonate according to whether the arrangement of atoms and ions that make up calcium carbonate is regular. In addition, there are nano calcium carbonate and so on.
