Synthesis and characterization of aluminum-yttrium perovskite powder using a co-precipitation technique

In this research the YAlO۳ perovskite powder (YAP) was successfully synthesized by co-precipitation route. Co-precipitation synthesis is simple and affordable technique that capable to produce more homogeneous powders. The temperature was lowered to ۱۴۰۰ °C as a result of the first step's investigation into how different mineralizers affect YAlO۳ formation. The next step involved examining the impact of pH on the synthesis process as well as the calcination time and temperature. The optimal conditions for the synthesis of single-phase YAP were subsequently determined. Scanning electron microscopy (SEM), inductively coupled plasma mass spectrometry (ICP-Mass), and X-ray diffraction (XRD) analysis have all been used to characterize the obtained powders. The findings demonstrate that the NaF:MgF۲:Li۲CO۳ (۳:۲:۱ by weight) was the most suitable mineralizer system for formation of YAlO۳ perovskite. In addition, powders of orthorhombic YAP were successfully synthesized at pH=۹. The optimal conditions for the preparation of single phase aluminum-yttrium perovskite crystals were found to be calcination at ۱۴۰۰ °C for ۴ hours.In this research the YAlO۳ perovskite powder (YAP) was successfully synthesized by co-precipitation route.
