Powder Classroom. Standard: Nano Calcium Carbonate (worth to be collected)

China Powder Network News

This standard applies to nanometer calcium carbonate powder materials. This product is mainly used in rubber, plastics, sealants, adhesives, coatings and inks.

Nano-calcium carbonate is a new ultra-fine solid powder material developed in the 1980s with a particle size between 0.01 and 0.1 μm. Due to the ultrafine refinement of nano-CaCO3 particles, the crystal structure and surface electronic structure change, resulting in quantum size effects, small size effects, surface effects and macroscopic quantum effects that ordinary calcium carbonate does not have.

Molecular formula: CaCO3

Relative molecular mass: 100.09 (according to 2007 international relative atomic mass)

Appearance: white powder

Crystal form: calcite, aragonite, vaterite, amorphous

Morphology: cuboid, nearly spherical, spindle-shaped, rod-shaped, chain-shaped, needle-like
