Abstract

Sintering of lime by one- and two- step calcination has been investigated. Samples obtained by double stage calcination always exhibit higher bulk density than those of single stage process. Fe2O3 helps in the sintering of CaO by liquid phase formation at the sintering temperature. The grain size of sintered lime is higher in the presence of Fe2O3 additive. Fe2O3 containing samples have improved hydration resistance due to their larger grain size compared to Fe2O3 free samples. Lime samples containing 4 wt. % Fe2O3 and sintered at 1600degreesC have CaO as the major phase with a small amount of dicalcium ferrite phase(C2F). The maximum flexural strength at 1300degreesC is achieved by the samples containing 2wt. % Fe2O3 and sintered at 1600degreesC.
