Abstract

MgNb2O6 single crystals of several cubic centimetres have been grown by the Czochralski technique. The as-grown black crystals were annealed in oxygen at high temperature and became transparent. The process was reversible by high temperature vacuum annealing. The optical absorption observed in as-grown samples has been attributed to oxygen deficiency of the crystal. The grown crystals were resistant against strong mineral acids. The surface tension of the molten material was 0.35 N/m.
