Around particle blast cleaning and peening bead, made from crystalline Zironia and closely bonded inside a silica glassy phase. This produces impact resistance and hardness which gives long life. These beads are environmentally friendly, as they produce virtually no dust. Can be used as a substitute for Glass Beads.
