FIELD: chemistry.
SUBSTANCE: invention relates to the production of zirconium tungstate powder (ZrW2O8), which can be used to produce shut-off elements of the oil and gas complex. The method comprises mixing zirconium powders (ZrO2) and tungsten oxide (WO3) in the ration 1:2 by mechanical activation with an acceleration of grinding bodies of 30-60 g with the addition of a surfactant in the form of an aqueous solution of sodium chloride. After activation, the powder mixture is placed in a quartz tube and heated at 1200±25°C followed by quenching to room temperature.
EFFECT: producing high-purity zirconium tungstate having a particle size of less than 2 mcm.
