Zirconia ball(AZ)- Yttria stabilized zirconia
ball. AZ zirconia balls show stability against heat at room temperature since they
are manufactured from raw materials in which Y2O3 is partially stabilized
into ZrO2. They show higher pulverization compared to other ceramic media due
to their superior characteristics such as mechanical strength, hardness, wear
resistance, etc., and show extremely low levels of impurities.
Their applications are as follow:
- Piezoelectric material, magnetic electric
material, dielectric material, fine ceramic, pigment dispersion, photo copier
toner, pharmaceuticals, foodstuffs, and textiles.
- Typical property:
