Particle shape of ground calcium carbonate

The shape of ground calcium carbonate is irregular, the particle size varies greatly, and the particles have certain edges and corners, the surface is rough, the particle size distribution is wide, the particle size is large, and the average particle size is generally 1~10μm. Ground calcium carbonate is divided into: coarsely ground calcium carbonate (> 3μm), finely ground calcium carbonate (1~3μm), ultrafine calcium carbonate (0.5~1μm ground calcium carbonate) according to its original average particle size (d). Powder characteristics: a. The particle shape is irregular; b. The particle size distribution is wider; c. The particle size is larger.
