The series of experiments have been conducted by the present authors to develop the solidification process for stabilization of sludges containing hazardous metals. In the previous works Cr₂O₃, which was took up as a model of sludge, was solidified by heating with the mixture of Na₂CO₃, CaCO₃and SiO₂and the leaching test was applied to determine the environmental adequacy of the ternary system Na₂O-CaO-SiO₂as chemical fixation agents. In the present study a small amount of active carbon was added on firing to examine the effect of reducing atmosphere on the concentration of chromium leached from the fired products.
