                                Chemical Name: Calcium Carbonate

                                Formula: CaCO3

                                Molecular weight:100.09

                                Properties:White fine powder without smell and taste. Its relative density is 2.5-2.7, hardly insoluble in water and enthanol, but soluble in lower density acid.(acetic acid, lower density hydrochloric acid and nitric acid).It is difficult to solubilize in lower density vitriol.

                                Specifications: GB 1886.214-2016/FCC V
