Calcination state: Calcination involves heat treating a powder to fuse it and enlarge its primary crystallite size. It has the effect opposite to that of milling. A highly calcined powder will have a low specific surface area, a large crystallite size, will require a very high sintering temperature, and will have low drying and firing shrinkage.

Calcination Temperature. Calcination temperature had strong influence on the physicochemical characteristics: its increase from 500°C to 800°C increased the solidsolution particle size (–) and decreased the SSA (186–45m2g−1), the relative amounts of Ce3+ and Mn4+ oxidation states, the reducibility, and, as a consequence of all the above, the alytic activity.

· So you can see that substracting LOI without relating to same basis makes you underestimate the calcination degree, but as you stated, the difference will come to zero if calcination is complete. You are also right that the dust cycle influences apparent calcination, but anyway, what is important is the material entering the kiln and cycled dust is part of this.
