FIELD: chemistry.
SUBSTANCE: invention relates to preparation of powdered sodium tungsten oxide bronzes using a chemical method. The mixture for preparing powder from the molten mass contains sodium tungstate and metaphosphate and tungsten oxide powder. The tungsten oxide powder is tungsten (IV) oxide with the following ratio of components in the mixture in mol %: Na2WO4 - 25-65, NaPO3 - 15-35, WO2 - the rest.
EFFECT: cheaper process and wider range of compositions of sodium tungsten oxide bronzes.
