Dilatometric inspection of phase changes in Mg-PSZ

A. I. B. Rondao et al.

Summary: By studying partially stabilized zirconia samples, the changes in phase composition and microstructure at different temperatures can be analyzed using dilatometry. The consistency of the dilatometry data analysis is verified through observations by scanning electron microscopy and X-ray diffraction analysis. The combination of room temperature XRD and dilatometry data provides comprehensive information about the changes in microstructure and phase content with temperature.

Fabrication and reaction mechanism of MgO-stabilized ZrO2 powders by combustion synthesis

Nan Lu et al.

Summary: In this study, MgO-stabilized ZrO2 powders were prepared by combustion synthesis. The diluent content significantly affected the combustion process and the properties of the resulting product. Increasing the diluent content led to decreases in combustion temperature, propagation velocity, and MgO content.

Phase stability and microstructure morphology of microwave-sintered magnesia-partially stabilised zirconia

Guo Chen et al.

Summary: This study introduced microwave heating into the preparation process of zirconia materials to improve stability and microstructure of MgO-partially stabilised zirconia (MgO-PSZ). The effects of microwave heating on phase stability, microstructure, and surface morphology were evaluated, showing that microwave treatment significantly increased the stability rate of MgO-PSZ sample. Additionally, a decrease in m-ZrO2 phase content and improvement in microstructure were observed in the microwave-sintered MgO-PSZ sample. This research provided optimal microwave heating conditions for enhanced performance of MgO-PSZ material and laid a foundation for further research on zirconia materials prepared using microwave heating technology.
