摘要：

Yttrium aluminum perovskite (YAP) is a promising high temperature ceramic material known for its, structural, mechanical and optical properties. YAP's 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 degrees C. The synthesized YAP's 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).
