Abstract
Partially Stabilized Zirconia samples with 7, 8 and 9 mol% MgO (Mg-PSZ) were sintered at 1700 °C for 2 h and cooled to room temperature (2 °C.min−1), to obtain distinct phase compositions and microstructures. These materials were studied by dilatometry (DIL) up to about 1500 °C (heating rate of 10 °C.min−1). A detailed analysis of DIL curves is used to estimate the initial M (monoclinic) phase content and quantify the progressive conversion M→T (tetragonal) as a function of temperature. Microstructures observed by scanning electron microscopy and phase content estimates from X-ray diffraction (XRD) patterns of sintered samples and milled powders, are used to show the consistency of the DIL data analysis. Furthermore, combination of room temperature XRD and DIL data yields unique and comprehensive details on the microstructural and phase content changes with temperature (all phases, M, T and C-cubic), hardly obtained in any other manner.
