Description

Using the methods of thermogravimetry, infrared spectroscopy and analytical analysis electroreduction of WO42- and MoO42- from fluoride-containing electrolyte is studied. It is established that products of incomplete reduction of tungstate- and molybdate ions present heterogeneous systems consisting of oxide-hydroxide compounds of lower valencies, possesing mixed conductivity. Complete reduction of WO42- and MoO42- to metal takes place at high concentrations of fluoride-ion (>= 50 g/l) and high current densities: 100-400 A/dm2 for molybdenum and 100-200 A/dm2 for tungsten
