Quicklime (Calcium Oxide) Carmeuse

Quicklime (Calcium Oxide) In the quicklime range of products, Carmeuse has high calcium quicklime and dolomitic quicklime products. The HIGH CALCIUM QUICKLIME is produced from limestone containing over 98% calcium carbonate. DOLOMITIC QUICKLIME is produced from limestone containing a mixture of both calcium and magnesium carbonates.

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.
