The physical and chemical properties of the calcined dolomite are very variable by the calcining conditions.
The calcining conditions of dolomite, that is, temperature and time at the heating, are discussed.
The thermal decomposition temperature of dolomite is about 900°C.If the dolomite has been heated for a long time at the higher than this temperature, the density of the calcine increases, but the reactivity grows worse.
The measurement of reactivity using the hydration of the calcine is described, and it is found that this method is very effective to control the conditions of the calcination.
