The aim of the examinations was to produce various dispersion ceramics in the range of 0 -100% Al2O3, and to determine the strengths and selected characteristics such as density, fracture toughness KIC, thermal conductivity, elastic modulus and hardness. Furthermore, the phase composition of all samples was examined by means of X-ray diffraction following Rietveld refinement. The examinations showed that the material parameters can be specifically influenced by the corresponding adjustment of the ZrO2 portion. The utilisation of the effects of the dispersion and transformation reinforcement can be exploited particularly with the mixture 20 % Al2O3-80 ZrO2(Y-TZP). Significant differences between the two forming procedures – slip casting and pressing – could not be established.
