The zirconium silicate beads are made from imported zircon sand, Rolled into a billet after fine grinding, and formed by a sintering phasing process. It has the characteristics of high compressive strength and low abrasion, and is widely used for superfine grinding of calcium carbonate, kaolin, titanium dioxide, paint, ink and other products.
The content of zirconia in the beads is approximately 65% and so it is usually called "65 Zirconium". With the advanced process of roll polishing and high temperature sintering, there will be no pore and void inside the beads. Because of medium density and hardness, it will be suitable for the grinding of materials with medium and low viscosity and it can be used in most of the grinding equipment. The small size beads are usually used as high0end ball blast for polishing and removal of flaws.
