Lanthanide aluminium perovskites LnAP – (Ln = La to Lu) have found application similar to that of yttrium aluminium perovskite (YAP). Among the LnAP we report the successful synthesis of some of the representative members of this family like lanthanum aluminium perovskites LaAlO3 (LAP), samarium aluminium perovskite SmAlO3 (SAP) and gadolinium aluminium perovskite GdAlO3 (GAP). These compounds are very well known in the application of an electric field during fabrication, flash memory devices, optical and catalyst, in microwaves laser, phosphors for white-LED Application, etc. These oxide ceramics were prepared by hydrothermal supercritical fluid technique using the co-precipitated gel as precursor material. The synthesised mono-dispersed polycrystalline materials showed a high degree of crystallinity. The resultant materials were characterized using powder X-ray diffraction for structure and phase identification, scanning electron microscopy with EDAX for elementary analysis. Energy dispersive X-ray analyses were performed for particle morphology, phase purity and stoichiometry.
