Paper Title:
Characteristic Properties of a New Dispersion Ceramic
  Abstract

The ceramic materials Al2O3 and ZrO2 proved successful in hip joint endoprosthetics for more than 20 years. The advantages of these materials are to be found in particular with the very good properties like biocompatibility and wear resistance; thus, they are clearly ahead of conventional materials like metal or PE. The increasing requirements regarding implants can only be realised by means of improvement of the used materials. That is why we surveyed utilisation of new dispersion ceramics consisting of Al2O3 and ZrO2. The first tests were aimed at characterisation of the material regarding material features and measurement of burst load at the hip joint heads. The results showed that both bending strength and burst load of the components could be significantly improved. Thus, the new ZTA dispersion ceramic is perfectly suitable for use with joint endoprosthetics.
