Synthesis of Perovskite-type LuA103 Single Crystals by KF-flux Method at Ambient Pressure

Abstract

Single crystals of perovskite-type LuAlO₃ were successfully obtained for the first time in air at ambient pressure by a flux method using KF. Single crystals are transparent colorless or pale red cubes. Size of the cubes are 30-60 μ m in edge. This compound belongs to orthorhombic system, space group is Pbnm, lattice parameters are a= 5.103 (5) Å, b= 5.332 (5) Å, c= 7.305 (7) Å. Contamination from the flux reagent to the crystals is not observed.
