Hydrothermal synthesis and characterization of orthorhombic yttrium aluminum perovskites (YAP)

Yttrium aluminum perovskite (YAP) is a promising high temperature ceramic material, known for its structural, mechanical and optical properties. YAPʹs also known as an ideal host material for solid-state lasers and phosphors. Polycrystals of yttrium aluminum perovskites were synthesized for the first time by employing hydrothermal supercritical fluid technique, in the pressure–temperature range of 100–200 MPa and 650–750 °C. The synthesized YAPʹs were characterized using powder XRD, SEM and EDAX studies. The X-ray diffraction pattern matches well with the reported orthorhombic YAP pattern (JCPDS-70.1677).
