SEM-EDS analysis of slip cast composite Al2O3-ZrO2 ceramics

In this paper, composite Al2O3–t-ZrO2 ceramics (composition: 95 wt. % Al2O3 – 5 wt. % t-ZrO2 and 90 wt. % Al2O3 – 10 wt. % t-ZrO2) was formed by slip casting in plaster mould. After drying, green bodies were sintered in laboratory electric kiln under air environment at a temperature of 1650 °C. Density of prepared samples was determined by the Archimedes' method. Surface morphology of sintered composite ceramics samples was determined by scanning electron microscope (SEM) equipped with energy dispersive spectrometer (EDS) analysis. Distribution of the elements aluminium (Al), zirconium (Zr) and oxygen (O) on fracture surfaces of sintered samples was determined by EDS mapping. SEM-EDS analysis of prepared composite ceramics samples confirmed the homogeneous distribution of ZrO2 in Al2O3 matrix.
