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.
