説明

The wettability between alumina ceramics and liquid aluminum was measured by the dip coverage method. The incubation period τ that preceeds wetting, was observed in all of the wetting processes. In the case of Al2O3-3%SiO2, the incubation period is short and the wetting rate decreases as compared with those of Al2O3-0.1%SiO2. The wetting process of alumina with liquid aluminum was analyzed by the same model of the nucleation rate as applied for the wetting process between SiC or graphite and liquid aluminum.<BR>The wettability between alumina and liquid aluminum was improved by alloying 1∼5% cerium or calcium that has greater affinity to oxygen and seems to increase the solubility of oxygen in liquid aluminum. However, lanthanum has little effect on the wettability except for the case of a higher content of 5%La and a higher silica contens of Al2O3-3%SiO2.
