INNOVNANO: YttriaStabilized Zirconia Powder
This company has developed 3 mol% yttria-stabilized zirconia powder (3YSZ), an advanced technical ceramic with medical device applications. Thanks to a uniform nanostructure and formation of a high stability phase under pressure, Innovnano’s 3YSZ reportedly combines extreme component strength and fracture resistance with enhanced biocompatibility, making it the ideal ceramic material for extended-life orthopedic implants, particularly knee and hip replacements. With advanced mechanical and tribological performance, as well as ageing resistance, Innovnano’s 3YSZ powder offers an attractive solution to medical implant manufacturers, which, through increased implant lifetime, can offer their customers reduced time, costs and morbidity through fewer repeat, invasive procedures.
Innovnano’s 3YSZ is manufactured using the company’s patented emulsion detonation synthesis (EDS) technology, which results in a highly pure, nanostructured ceramic powder with desirable homogeneity and an even distribution of yttria. Stemming from the powders’ nanostructure, the 3YSZ can be sintered at lower temperatures to keep grain size to a minimum. The resulting high-density ceramic provides excellent mechanical performance and exceptional bending strength—an essential property for orthopedic implants that are put under constant mechanical stresses and strains. In addition, the small grain size leads to enhanced material stability and, in turn, increased resistance to hydrothermal ageing.
