Superfine heavy calcium carbonate

Superfine heavy calcium carbonate
 
    

white powder, water insoluble, acid soluble. white powder, colorless, tasteless. Stable in air. Hardly water insoluble, alcohol insoluble. Heat to 898℃, the product can dissolve into calcium oxide and carbon dioxide. The product has high purity and heating stability. It will not dissolve under 400℃, High Whiteness , Oil is low, the refractive index is low, soft, dry, non-crystalline water, the hardness value of small low wear, innocuity, tasteless, odorless, good dispersion etc.

   
[Package]  25（kg/bag）stored and transported with inner plastic outer knitting bags and avoid water, or packed according to the requirement of the customers.
