  Influence of calcination temperature on the physical and …

  202441 · This paper presents how the physical and chemical characteristics of clays are progressively influenced as the calcination temperature is increased with a special focus on under and over calcination. The comparison of physical and chemical characteristics gives a better understanding of when and how optimal reactivity can be achieved.
