Zirconia ball

Zirconia ball Description

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.
