Chemical Composition
 
 
The material of Torayceram* beads and balls is mainly tetragonal zirconia made from zirconium oxide to which yttrium oxide is added, achieving the highest strength of all ceramics materials. Furthermore, they are almost free from contamination of impurities such as SiO2, Fe2O3 and MgO.
