Abstract

In this study, pure (with no additives) and mill scale (98.66 wt.% Fe2O3 content) added (up to 1.5 wt.%) natural dolomite of Selcuklu-Konya-Turkey fired at 1600-1700 degrees C for 2-6 h using the one-stage process. The resulting bulk densities and apparent porosities of the sintered doloma are investigated. According to the results of experiments with 15 sintered samples, sintering temperature, soaking time and increase of mill scale amount were found to increase the bulk density and thus decrease the observed apparent porosity.
