Mechanical properties and microstructural features of six commercial 3 mol% Y-TZP and one 6 mol% Mg-PSZ materials are evaluated. The difficulties of X-ray phase analysis are discussed. Grain sizes varied between 0.4 and 0.7 μm in TZP materials. Some bigger grains, grain size of several micrometers, were found. Their yttria content, measured by EDX, was higher than in smaller grains. The monoclinic phase content in TZP materials varied in the range of 0–10% in the surface but in the bulk no monoclinic phase was detected. In some TZP materials there was found up to 10% cubic phase. Strength values were evaluated by 4-point bending tests and fracture toughnesses, by indentation technique. Fracture surface analysis was performed by using SEM.
