Detailed Project Report on quick lime powder

QUICK LIME POWDER
[CODE NO 3389]  

Quicklime (or calcium oxide (CaO), or burnt lime, or unslaked lime), is obtained by calcining (controlled heating - time and temperature) limestone at temperatures above 900°C. This highly reactive product is essential to many industrial processes

It is also known as caustic lime. It is obtained by calcination (i.e. heating to redness) of comparatively pure lime stone. It is amorphous in nature, highly caustic and possesses great affinity to moisture. Quicklime is also known as burnt lime.

Quicklime (calcium oxide) is a white solid having a crystalline structure. Quicklime is highly reactive with water, generating considerable heat in the hydration process. It can be bought at masonry supply stores.

Quicklime is the compound which is used commonly for whitewashing houses. The chemical name of quick lime or lime is calcium oxide. The chemical formula of quicklime is CaO.
