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.

Calcium carbonate manufacturing process

Calcium carbonate is usually divided into heavy calcium carbonate/ ground calcium carbonate powder and light calcium carbonate/ precipitated calcium carbonate. Heavy calcium carbonate is also called ground calcium carbonate, referred to as heavy calcium carbonate/ ground calcium carbonate powder, which is produced by physical processing method; light calcium carbonate is also called precipitated calcium carbonate

Effect of process conditions on spray dried calcium

Aug 18, 2020· A series of spray drying experiments were carried out on calcium carbonate powder, to investigate the effect of three variables (gas flow rate, solids loading, and feed flow rate) on the yield and particle size of spray dried calcium carbonate. Porous, hollow spherical particles ranging between 14 201 μm were formed in a lab-scale spray drier.

Calcium carbonate Essential Chemical Industry

Calcium carbonate (limestone) is heated to form calcium oxide (quicklime) and carbon dioxide: It is an endothermic reaction and the equilibrium lies far to the left at low temperatures. Only at about 1200 K does the partial pressure of carbon dioxide exceed atmospheric pressure and the decomposition proceeds to completion.

Calcination Wikipedia

The process of calcination derives its name from the Latin calcinare (to burn lime) due to its most common application, the decomposition of calcium carbonate to calcium oxide and carbon dioxide, in order to create cement.The product of calcination is usually referred to in general as "calcine", regardless of the actual minerals undergoing thermal treatment.
