Calcium Carbonate is a white powder or colorless crystals, and is odorless and tasteless. It is very slightly soluble in water (a few ppm), and soluble in acids with evolution of carbon dioxide. Calcium Carbonate is one of the most stable, common, and widely dispersed materials, and occurs in nature as aragonite, oyster shells, calcite, chalk, limestone, marble, marl, and travertine.
Calcium Carbonate applications include: Source of lime; neutralizing agent, filler, and extender in rubber, plastics, paints; opacifying agent in paper; fortification of bread; putty; tooth powders; antacid; whitewash; Portland cement; sulfur dioxide removal from stack gases; metallurgical flux; analytical chemistry; carbon dioxide generation (laboratory).
Please see Calcium Carbonate (Pulverized Limestone) Safety Data Sheet for full safety and compatibility information.
