Tokyo, Japan—Tosoh Corporation and the Graduate School of Engineering at The University of Tokyo, a renowned national university, have recently published a paper in the prestigious scientific journal, Proceedings of the National Academy of Sciences. The paper highlights the significant progress achieved by Tosoh in the development of Zgaia 1.5Y-HT, an environmentally friendly zirconia powder.
Tosoh and The University of Tokyo obtained the results through the Next Generation Zirconia Social Cooperation Program established at The University of Tokyo on July 1, 2020. They clarified the morphology and functional expression of Zgaia 1.5Y-HT—an ultrahigh toughness grade of zirconia that revolutionized the industry—through atomic-scale microstructural analysis using cutting-edge electron microscopy.
Through this social cooperation program, Tosoh will continue to train and cultivate talented people capable of significantly improving zirconia ceramic properties and promoting high-level material development research. At the same time, the company will push technological development forward to resolve various social issues, with the ultimate goal of contributing to the realization of a sustainable society.
