Zirconia, a ceramic material, is getting more attention for its favorable physical, biological, and corrosion resistance attributes. Zirconia demonstrates polymorphism, and upon cooling, it exhibits martensitic transformation. This results in the uncontrolled expansion of the volume of about 5% and makes it suitable for clinical load bearing application. However, it can result in material catastrophic failure. By introducing a dopant into its crystal structure, this transformation can be stabilized, controlled, and the material becomes fracture-resistant under load-bearing situations. Ceria is isovalent with zirconia and does not create any vacancies upon substitution. In this study, 20 mol % Ceria Stabilized Zirconia (Ce-TZP) has been characterized upon sintering at three different temperatures, such as 1400°C, 1500°C, and 1600°C for 2 hours. X-ray Diffraction Pattern and Raman spectroscopy confirmed the tetragonal phase, and while analyzing the Scanning electron microscopy images, the increase in grain size is confirmed with sintering temperature. If the tetragonal phase can be confirmed with no change in the grain size distribution and surface roughness, Ce-TZP can be considered aging resistant, which is an important property to consider Ce-TZP as a prospective dental implant material.
