Abstract
Sintering of raw dolomite and hydroxides derived from dolomite was carried out in the temperature range 1350–1650 °C. The hydroxide derived from dolomite was developed through pre-calcination of dolomite followed by its hydration. For hydroxide development, after precalcination one sample was air-quenched and the other powder was furnace cooled before hydration. The air quenched samples showed better densification than that of the furnace cooling process at the same temperature. Fe 2O 3 addition enhances sintering by liquid formation at higher temperature. The grain size of doloma with Fe 2O 3 addition is bigger than that without additive. Hydration resistance was related to densification and grain size of sintered dolomite.
