Precipitated calcium carbonate (CAS: 471341) is produced industrially by the decomposition of limestone to calcium oxide followed by subsequent recarbonization or as a byproduct of the Solvay process (which is used to make sodium carbonate). Precipitated calcium carbonate is purer than ground calcium carbonate and has different (and tailorable) handling properties.
Water hardness (Calcium in water) is measured in grains per gallon (GPG) or milligrams per liter (mg/l, equivalent to parts per million, or ppm). Water up to 1 GPG (or mg/l) is considered soft Water from 1 to GPG is considered moderately hard. Water from to 7 GPG is Hard Water. Water from 7 to GPG is Very Hard. Health Concerns:

By processing calcium carbonate from marble, one obtains precipitated calcium carbonate, which is ground into a powder called ground calcium carbonate. Ground calcium carbonate has many industrial, medicinal and pharmaceutical uses. In the construction industry, limestone is necessary for making lime mortar. Likewise, marble is a building material also used in this industry. In different manufacturing .

Apr 02, 2012· A 40% PVC paint formulation was tinted to a light green, and separate panels were made using a 12micron calcium carbonate, a 1micron coated calcium carbonate and and a 2micron nepheline syenite. Three panels of each were placed in the salt fog cabinet using deionized water adjusted to a pH 4 (acid rain is usually 4 to ) using sulphuric acid.
Calcium carbonate occurs naturally as the principal constituent of limestone, marbel and chalk. Natural ground Calcium carbonate has been used for years as the primary constituent of putty. Since 1945, the processing of natural Calcium carbonate has seen the introduction of beneficiation by flotation to remove impurities and the development of grinding processes to manufacture finer products.
