Tosoh has developed Zgaia series zirconia powder, through the redesign of the particle structure, the sintering temperature from 1500℃ to 1250℃ , so as to achieve the effect of energy saving and emission reduction.

Tosoh said that the Zgaia series grade 1.5Y-HT powder, yttrium oxide content of 1.5 mol%, while having excellent bending strength and fracture toughness, is currently the world's lowest yttrium stabilized zirconia content.

1.5Y-HT yttrium oxide content is lower than previously, Thus, the fracture toughness and bending strength which cannot be achieved by traditional zirconia are realized.

 

In addition, the highly durable powder of the new grade:3Y-LD ensures the uniform distribution of yttrium oxide by an original method, and the uniform microstructure inhibits hydrothermal degradation.

A four-year accelerated degradation test of the sintered material immersed in 140℃ water showed almost no deterioration, fully confirming the exceptional durability of Zgaia 3Y-LD.
