Zirconium Silicate Beads By Far Ocean Zirconia Co.,ltd

Zirconium silicate beads are shaped in electrolyte solution and hardened at a high temperature in kiln. Compared to electro fused zircon beads and the similar others, they have homogenous microstructure and no air pockets. This give them 1/2 lower beads wear rate than the others. The middle density and hardness features are suitable for grinding slurry in viscosity from low to middle. The small sizes are the high quality blasting and penning media.

Features:
High crushing strength,
Higher gravity,
High spheroid: 96% spheroid,
Smooth surface: Deeply polished surface.
