The corrosion behaviors of various oxide ceramics against a molten slag were investigated in order to find candidates of chrome-free refractory, and were classified into four categories : low wettability and low reactivity (Cr_2O_3) ; high wettability and high reactivity (MgO, Y_2O_3) ; low wettability but high reactivity (Al_2O_3) ; high wettability but low reactivity (ZrO_2, YAG). The reactivity was also supported by thermodynamic simulation. As a result, ZrO2 was proposed as candidate material because of the low solubility in molten slag.

研究了各种氧化陶瓷对熔融炉渣的腐蚀行为，以查找无铬的难治性的候选者，并分为四类：低润湿性和低反应性（CR_2O_3）；高润湿性和高反应性（MGO，Y_2O_3）;低润湿性但反应性高（al_2o_3）;高润湿性但反应性低（ZRO_2，YAG）。热力学模拟还支持反应性。结果，由于熔融炉灶的溶解度较低，因此提出了ZRO2作为候选材料。
