Abstract��The hydrides in industrial lime, alumina, magnesia and calcium fluoride were investigated through differential thermal analysis, X-ray diffraction. The characteristic of losing weight during heating up for them had been studied by thermogravimetric analysis method. Results indicate that industrial alumina, lime, magnesia, which have more moisture or hydride mainly including ��-Al2O3, Ca (OH)2 and Mg(OH)2, and losing weight more during thermogravimetric analysis process. However, the weight of premelted slag consisting of lime, fluorite, alumina and magnesia lose almost nothing, which means no hydride in it. Some relationship for calculating the weight loss process had been established according to results of thermogravimetric analysis. These results will be in favor of setting up the rational calcination criterion for slag used in electroslag remelting process.
