Abstract

In this work, the conditions for preparation of raw material as well as the conditions for crystal growth of (gamma) - LiAlO₂ and (beta) -LiGaO₂ by Czochralski method were studied. As a result, single crystals of these compounds were obtained. The phases were checked by x-ray powder diffraction. High vapor pressure of the melt at the pulling temperature was identified as the main problem in the growing process. Preliminary high-resolution x-ray diffraction measurements were made, which indicated a high concentration of small defects in the LiGaO₂ crystals.
