Calcium carbonate CaCO3 PubChem

Precipitated calcium carbonate (CAS: 471-34-1) is produced industrially by the decomposition of limestone to calcium oxide followed by subsequent recarbonization or as a by-product 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.

US20050276897A1 Ultra-dry calcium carbonate Google

In accordance with the present invention, precipitated calcium carbonate which has been dried e.g. by using a belt dryer, having a residual moisture content of 0.1 to 3% by weight, in special cases up to 80% by weight residual moisture content, is subsequently dried using microwaves.

under dry or wet conditions depending on the final product requirements. Ground Calcium Carbonate (GCC) differs from Precipitated Calcium Carbonate (PCC) in that the GCC is formed directly from grinding limestone rock into a powder, while PCC is chemically produced and precipitated out as powder. 1.2. Precipitated calcium carbonate (PCC)

Calcine (heat) in a kiln to 1850° F, which takes the calcium carbonate apart, forming lime (CaO) and carbon dioxide gas (CO2). The carbon dioxide can be captured for reuse. CaCO3 + Heat → CaO + CO2 ↑. Add the lime to water to form calcium hydroxide (hydrated lime or slake). CaO + H2O → Ca (OH)2.

Grades of calcium carbonate suitable as fillers for plastics are obtained from naturally occurring deposits as well as by chemical precipitation. The natural types are prepared by dry grinding, yielding particles usually over 20 μm, used in stiff products such as floor tiles; or by wet grinding, yielding particles under 16 μm, used in flexible products.
