Claims (1)

Способ получения пятиокисей тантала и ниобия путем нагревания исходного ниоботанталового материала со смесью серной кислоты и сульфата аммония с последующим выщелачиванием полученного сплава водой или растворами кислот и выделением конечного продукта из раствора фильтрацией, сушкой и прокалкой полученного осадка, отличающийся тем, что в качестве исходного ниоботанталового материала используют комплексные полимерные соединения тантала и ниобия, которые обрабатывают смесью серной кислоты и перекиси водорода для экстрагирования ниобия и тантала в водную фазу, гидролизуют ниобий и тантал разбавлением водой, а полученные гидроксиды сплавляют со смесью серной кислоты и сульфата аммония.The method of producing tantalum and niobium pentoxide by heating the source of niobotantalum material with a mixture of sulfuric acid and ammonium sulfate, followed by leaching the resulting alloy with water or acid solutions and isolating the final product from the solution by filtering, drying and calcining the precipitate obtained, characterized in that as the source of niobotantalum material use complex polymer compounds of tantalum and niobium, which are treated with a mixture of sulfuric acid and hydrogen peroxide to extract nio of bium and tantalum into the aqueous phase, niobium and tantalum are hydrolyzed by dilution with water, and the resulting hydroxides are fused with a mixture of sulfuric acid and ammonium sulfate.
