Abstract

In this project, the BOXITE was examined to determine its thermal behavior for production of fire-bricks. Some samples were burned at temperatures of 1100, 1200 and 1300 °C for 5 hours. The porosity and density of the samples was determined after burning. The chemical and mineralogical compositions of the raw and burned material was determined by using XRF and XRD, which the constituent minerals of the raw material was diaspore, boehmite, kaollinite and anatase. The burned BOXITE consisted of mullite, silica, corundum and rutile. TiO2 undergoes a phase transition when heated and expands at high temperatures which may lead to cracks in the fired material. The high porosity of BOXITE at 1300 °C can be the result of cracks made by expansion of TiO2 or be the result of exit of lattice water of diaspore, boehmite and kaolinite minerals. The presence of about 3% of TiO2 in refractory soil increases the total and average porosity. According to the data resulting of examinations, the best temperature to SINTERING this BOXITE is 1200 °C.
