| Research Abstract |
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.
