Complete Phase Change of Y2NiMnO6 Ceramics Doped with TiO2 at High Temperature
Determining the structure of ceramic materials is essential in order to fully characterize the electrical properties and improve existing materials. YMNO ceramics (Y2NiMnO6) prepared by compression and sintering were doped with TiO2 and analyzed using XRD and SEM. The calcined sample prior to sintering contained phases of the YMNO double perovskite and TiO2. Following sintering at 1400°C, the perovskite structure was replaced by Y2Ti2O7 fcc structure, and the grain size was found to increase with sintering time up to 18 hours. This sets a limit to the amount of TiO2 which can be used to successfully dope the YMNO ceramic.
