Solid solution Li2MoO4 – Li2WO4 crystal growth and characterization

Abstract Solid solution Li 2 Mo 1−X W X O 4 crystals were grown from two different melts (X=0.85 and 0.95) by Czochralski technique. The crystals were colorless and transparent within 300–1100 nm wavelength range. They had dimensions of 25 mm diameter and 100 mm length. The crystal grown from the X=0.85 melt had an inhomogeneous composition which varied from 0.65 to 0.88. The crystal grown from the X=0.95 melt had a uniform distribution of X, corresponding to the average Li 2 Mo 0.08 W 0.92 O 4 composition. Both crystals belong to a phenacite-type structure and they were characterized by X-ray diffraction, Raman and IR-spectroscopy.
