Quicklime - Preparation, Properties, and Applications with ...

Quicklime is also referred to as handpicked lime, burnt lime, lump lime, calcining lime, and caustic lime. It is known to be a caustic material that is prepared at approximately 900 degrees Celsius by burning calcium carbonate limestone, carbon dioxide is forced off at this high temperature, and the limestone is converted to Quicklime.

Quicklime preparation - Gebr. Pfeiffer

Quicklime reacts with water, generating a great amount of heat. We distinguish soft-burnt lime, medium-burnt lime, and hard-burnt lime. In the construction industry, quicklime is added to mortar. It can also be used as a drying or neutralizing agent, as fertilizer lime and for the production of lime mortar and lime plaster.

Chapter 7 Historical Overview of Lime Burning

Lime is made by the process of cakining limestone, that is, burning Che limestone without fusing (melcing) it. Pure lime (quicklime, burnt lime, caustic lime) is composed of calcium oxide-. When tre.ated with water, lime gives off heat, forming calcium hydroxide. and is sold commercially as slaked (or hydrated) lime.
