- Zirconia (Tosoh)
Zirconia is a uniquely advanced high-quality ceramic; a chemical compound having the formula Zr O2. Tosoh’s yttria-stabilised zirconia powder (YSZ) uses a hydrolysis process which ensures uniform dispersion of ytrria, and exhibits superior mechanical properties of high strength and flexibility. As a technological breakthrough, YSZ surpasses the strength limitations of traditional fine ceramics. Zpex Smile is the first full contour solid zirconia to combine natural translucency, high flexural strength and lifetime permanence for anterior teeth restorations. Heat insulating properties and oxygen-ion conductivity indicate it has potential for use in a variety of applications, from telecommunications to the new energy of the future, and environmentally beneficial products.
Tosoh is a pioneer of the development of YSZ and has become the major supplier worldwide, earning a solid reputation for consistent high purity and quality. Tosoh continues to focus resources in R & D and customer services for the ultimate evolution of zirconia. Basic grades are available for fine ceramics and solid electrolyte with oxygen-ion conductivity, plus easy mouldability “S” grades, “B” binder grades, ATZ “A” grades, and injection moulding compounds. Key Properties: High strength, flexibility, high purity.
