Phase microstructure and morphology evolution of MgO-PSZ ceramics during the microwave sintering process

In the present study, controllable microwave sintering was applied to prepare partially stabilised zirconia ceramics with enhanced phase composition and a more uniform structure. To reveal interface properties structural changes of PSZ during process, XRD, FT-IR, Raman, SEM characterisations were utilised. XRD analysis Raman demonstrated that increase temperature promoted martensite conversion. However, prolonging duration time unconducive retention stable phase. Additionally, FT-IR characteristic peak movement caused by reversible transformation observed. Furthermore, found treatment improved grain size structure distribution as-received MgO-PSZ sample. This work constructed technical prototype preparing via sintering, which can provide theoretical basis experimental for further industrial production.
