HOLLOW SPHERICAL STABILIZED ZIRCONIA AND PRODUCTION THEREOF

摘要

PURPOSE:To efficiently produce hollow spherical stabilized zirconia satisfying prescribed conditions by adding a stabilizer to baddeleyite ore, melting them and blowing air on the resulting molten slag to scatter the slag. CONSTITUTION:A stabilizer is added to beddeleyite ore and they are melted. When the resulting molten slag is discharged, air is blown on the slag to scatter and sphere the slag. Hollow spherical stabilized zirconia having 0.5-5mm diameter and 0.8-2.1g/cm3 bulk specific gravity is efficiently produced.
