O from 300 to 600oC, the crystallite size of CaO decreased which in turn increased the surface area of the catalysts. However, further increasing calcination temperature at 700 and 800oC lead to sintering of fine crystals, promote cluster agglomeration (Boynton 1980) and resulted in reduction of surface area.

GENERAL PRINCIPLE OF EXTRACTION prepareforchemistry

This method is based on the principle that impurities are more soluble in the molten state of metal (the melt) than in the solid state. In the process of zone refining, a circular mobile heater is fixed at one end of a rod of impure metal. As the heater moves, the molten zone of the rod also moves with it.
