Abstract
The invention relates to a mixture of fused grains having the following chemical composition, in weight percentages on the basis of the oxides: less than 55% of AlO; more than 35% and less than 80% of TiO; more than 1% and less than 20% of MgO; more than 0.7% and less than 20% of ZrO; and less than 20% of SiO, said fused grains also corresponding to the following composition, in molar percentages, on the basis of the single oxides AlO, TiO, MgO, ZrO: 90<2a+3m<110, 100+a<3t<210−a with a+t+m+zr=100, in which: a is the molar percentage of AlO; t is the molar percentage of TiO; m is the molar percentage of MgO; and zr is the molar percentage of ZrO. The invention also relates to a ceramic product obtained from such fused grains.
