Light And Heavy Basic Cmgo3 Magnesium Carbonate With Cas 13717-00-5
Magnesium carbonate is a white odorless powder, which has two common forms: amorphous powder and monoclinic crystal. It is characterized by non combustion and easy texture, and can be used as a fire insulation material for heat insulation and high temperature resistance.
