High-alumina ceramics (> 96 wt% Al2O3), with high densification and excellent abrasion resistance that makes them suitable for use as a grinding medium, were prepared from an Al2O3-MgO-SiO2-CaO-Tb4O7 (AMSCT) system. The influences of Tb4O7 addition on the densification, abrasion resistance, crystalline phase, micro-morphology and grain size of the ceramic materials were investigated. The experimental results indicate that the densification and abrasion resistance of the ceramics improved with

This study aimed to improve the purity and performance of alumina ceramics used as ball milling media. High-alumina ceramics (> 96 wt% Al2O3), with high densification and excellent abrasion resistance, were fabricated by the cold isostatic pressing method. The effects of adding the rare earth Tb4O7 on the densification, abrasion resistance, crystalline phase, micro-morphology and grain size of the ceramics were studied. The experiment results showed that the densification and abrasion resistance of the samples increased with Tb4O7 addition. The...
