Difference Between Calcination and Sintering

A typical example of calcination is the production of lime from limestone. In this process, limestone is given a high temperature that is enough to form and release carbon dioxide gas. Lime is produced in an easily powdered condition. What is Sintering? Sintering is a pyrometallurgical process in which small particles of metal are welded together.

In normal course lime gets first hydrated and then gets converted into calcium carbonate by the action of CO2. The complete process of calcination and conversion back to calcium carbonate is known as lime cycle. The normal lime cycle is shown in Fig 1.

A highly calcined powder will have a low specific surface area and a large crystallite size; it will require a very high sintering temperature and will have low drying and firing shrinkage. It is good for refractories or plasma spraying, but not for sintering into a ceramic. RSSC feedstocks are inherently coarse powders. Calcining is not required.
