Zirconia is a versatile material with fascinating physical and chemical properties. When stabilized with yttria, it is useful across a range of industries, especially for demanding industrial applications that require high strength, as well as wear and fracture resistance. 3 mol% yttria-stabilized zirconia (3YSZ) has been widely used in structural ceramic applications for many years due to its excellent mechanical properties, including high flexural strength and good fracture toughness when compared with other technical ceramics.

It is now possible to use a different material—2 mol% yttria-stabilized zirconia (2YSZ)—that provides all the benefits of 3YSZ, but with higher fracture toughness values.* At the same time, damage tolerance and resistance to aging are improved in this alternative option for any application that requires strong and long-lasting materials.
