Abstract

The process of coprecipitation of iron and tungsten from aqueous solution containing Fe(III) and tungstate ions in the presence of citric acid has been investigated. The element and phase composition of precipitates in the Fe–Al–W system has been evaluated. The synthesized precipitate particles were shown to repeat the shape and size of the initial aluminum matrix, have a developed surface, and comprised solid tungsten solutions in iron in the presence of the elemental aluminum phase.
