ZsBeads are sintered zirconium silicate grinding media with a high sphericity. In contrast to grinding beads that are produced in a melting process the ZsBeads are almost free of bubbles and pores. These properties increase their wear-resistance and prevent breaking. They are available in different fractions ranging from 0.6 mm to 1.8 mm.

It has been found that sintered materials can be obtained at a low Al 2 O 3 content (up to 5 wt %) at 1500–1550°C. It is also possible to intensify the sintering process by introducing additives that form a melt and cause liquid-phase sintering. Sodium silicate Na 2 SiO 3 (5 wt %) with a melting point of about 1072°C was used as an additive ...
