	High-Brightness Calcium Carbonate

High-brightness calcium carbonate of nano-class we supply is used into the fields of Paint, Paper, Coating, Plastics, Ink, Medicine, Food and so on. We can distribute differrent crystals and particle size nano calcium carbonate for different needs, and menu-service for our customers.

This product, with special technology, high-brightness and uniform particle characteristic, have all kinds of characteristics of nano particle and normal Calcium Carbonate.

Because the nano-metre particle of Calcium Carbonate is changed about the particle construction and the electronic construction of particle surface, it had taken to the quantum effect, the macroscopic quantum effect, small size effect and surface effect. Compared with normal regular materials, it has many special functions.
