By: Innovnano Innovnano’s 3YSZ is manufactured using the company’s patented Emulsion Detonation Synthesis (EDS) technology, producing 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 orthopaedic implants which are put under constant mechanical stresses and strains. Furthermore, thanks to the small grain size, the 3YSZ ceramic shows enhanced material stability and, in turn, increased resistance to hydrothermal ageing. With ever-increasing life expectancy, orthopaedic implants need to be able to stand the test of time, with minimised requirements for revisional surgery. Usually, under significant or repeated stress, a crack can begin to form on the surface of the implant, which over time can cause it to fail. With Innovnano’s 3YSZ, this same stress induces the 3YSZ to undergo structural transformation which acts to compress any crack, delaying or preventing its growth, and subsequently improving the fracture resistance. It is this phase transformation which can therefore increase the lifetime of joint replacements. For more information please visit the Innovnano website, www.innovnano- End
