A composite material consisting of aluminium oxide as a ceramic matrix and zirconium oxide dispersed therein. A method for the production thereof, components containing the composite and methods of using the same are also provided.

Ceramic composite material consisting of aluminium oxide and zirconium oxide as the main constituents, and a dispersoid phase

An intervertebral disc endoprosthesis for implantation in the spinal column, with an upper end plate and a lower end plate for securing respectively to the bones of the vertebral body, and with a slide bearing which is arranged between the end plates and is composed of slide bodies that are designed to slide on each other. both end plates are made of plastic and the slide bodies are made of ceramic, the slide bodies are encapsulated by the plastic of the end plates and the surface areas of the slide bodies encapsulated by the plastic of the end plates have surface area enlargements by comparison with flat surfaces. To ensure that the slide bodies are connected fixedly to the end plates in a manner secure against twisting, it is proposed that the surface area enlargements are elevations or depressions on the slide bodies.

Intervertebral disc endoprosthesis

Hardness, ageing resistance, wetting behavior in relating to water and high thermal conductivity are known characteristics of sintered molded bodies consisting of aluminum oxide; high strength and a high resistance to cracking, i.e., damage tolerance are known characteristics of sintered molded bodies consisting of zirconium oxide. These properties are combined in a material having a large fraction of aluminum oxide, zirconium oxide and optionally strontium aluminate.
