Calcium Carbonate Powder, Lab Grade

Calcium Carbonate, a whitish or colorless powder, is odorless and is largely water-insoluble at ambient conditions. The mining of limestone leads to the production of pure Calcium Carbonate that can be used as a dry powder or in slurry form. Calcium Carbonate PPT (Precipitated) Powder is a white, micro-sized substance made from naturally occurring pure limestone lumps. Industrially, precipitated calcium carbonate is also produced as a by-product of the Solvay process (synthesis of sodium carbonate). Its purity is much higher than the regular Calcium Carbonate and has unique (and tailorable) handling characteristics. Chemically pure or Laboratory reagents are the two terms often used to describe Lab Grade chemicals. Lab Grade chemicals do not meet any accepted quality or purity requirements such as the ACS Grade, the USP Grade, and the FCC Grade, despite their acceptable purity.
