摘要：
A method based on two-stage sublimation purification for obtaining high-purity tungsten (VI) oxide was developed. An impurity analysis of a commercial preparation of tungsten (VI) oxide was performed using mass spectrometry with inductively coupled plasma. Potassium-gadolinium-tungstate [KGW] crystals grown using commercial reagents and tungsten (VI) oxide with chemical purity of 99.999 wt.% were obtained. Acomparative analysis of crystals grown from different initial tungsten oxides was performed. It is shown that the developed high-purity tungsten (VI) oxide does not reduce the chemical purity of the grown KGWcrystals and is a promising raw material for the technology of glass-ceramic optical materials based on tungstates.
