Calcination, the heating of solids to a high temperature for the purpose of removing volatile substances, oxidizing a portion of mass, or rendering them friable Calcination, therefore, is sometimes considered a process of purification A typical example is the manufacture of lime from limestone...

Calcine, Calcination

The calcining process is used to remove some or all unwanted volatiles from a material eg H 2 O, CO 2, SO 2 and/or to convert a material into a more stable, durable or harder stateVarying temperatures are employed to calcine various materials, depending on the decomposition temperature of the volatiles being burned out and the degree of sintering desired in the product...

Evolution of the Surface Area of Limestone during ,

The calcination reaction of limestone is always companied by sintering of the calcined product In addition, accelerated sintering rates and a reduced specific surface area are observed in the presence of steam and carbon dioxide To simulate the change of surface area and the porosity of limestone samples in a simultaneous calcination and sintering process, a combined model based on both a ....
