Mixture of molten alumina-zirconia grains |
摘要 |
The mixture of molten alumina-zircon grains has the following chemical composition in percentage by weight to give 100%: 40-45.5% ZrO+HfO2; 46-58% Al2O3; 0-10% additive; <0.8% SIO2 and <1,2% impurities. The mixture is characterised in that the degree of impurity-containing grains is less than 2% and the nodule concentration measured on the section of any grain of the mixture is greater than 500 nodules per mm2 in at least 50% of cases.
