3.12.11.1Calcium carbonate (chalk, whiting, Paris white) Colour Index — CI Pigment White 18. Formula— CaCO3. Naturally,calcium carbonateis obtained from chalk or limestone. It is often known as whiting and is obtained in its natural state with a purity of around 96%. ...
Physical properties Calcium carbonate has the molecular formula of CaCO3and the molecular weight of 100.0924 g/mol. It is a common substance found in rock in all parts of the world, and is the main component of the shells of many marine organisms such as snails and conches. It is the ma...

Key outstanding problems include understanding the structure of amorphous calcium carbonate and rationalizing its metastability as an amorphous phase. Here we report high-quality atomistic models of amorphous calcium carbonate generated using state-of-the-art interatomic potentials to help guide fits to X...
Aragonite, widespread mineral, the stable form of calcium carbonate (CaCO3) at high pressures. It may be distinguished from calcite, the commoner form of calcium carbonate, by its greater hardness and specific gravity. Aragonite is always found in deposi
Calciumcyanamide can be used as afertilizer because it reacts with waterto give ammonia and calcium carbonate:CaCN2(s) + 3H2O(l)→ CaCO3(s) +2NH3(g)It is also used in the production ofmelamine, urea, and certain cyanidesalts. View all Production Methods Calcium cyanamide was first ...
