In several plants,a few NH4C1 are added to Al2O3 (as a packing material) during the activated sintering process of sintered carbides in order to lower the sintering temperature from 1450℃ to about 1250℃, whereas corundum tubes of sintering furnace deteriorate abnormally, A thermodynamical analysis has been given in this paper to exlpain the deterioration mechanism. It is shown that the cause of the abnormal deterioration of corudum tubes is that the CaO impurity, as a constituent included in tube material, reacts chemically with HCl gas decomposed from NH4Cl at high temperature. The conclusion has been verified by experiments and it will not be affected by the existent forms of different impurities.
