It is manufactured by thermal/electric fusion of oxides developing high impact properties combined with hardness. It is widely used in aerospace industry for shot peening application where the ceramic media can achieve peening intensities similar to that of steel shot but with a lower surface profile. High density of ceramic bead will help to achieve peening intensities similar to glass beads at a reduced abrasive velocity and results in less abrasive breakdown and less dust. The lower breakdown rate will result in a consistent blasting profile
