Abstract
A technique has been developed for producing iron oxide pigment based on galvanic waste. The effect of the norm, concentration and nature of the precipitant, temperature and time on the deposition of Fe(OH)3 was studied. To determine the effect of the nature of the neutralizer on the phase composition of the pigments, an X-ray phase and thermogravimetric analysis was carried out. It was established that the main phase is Ca2Fe2O5, and p-Ca2SiO4 is present as an impurity. The basic physicochemical properties of the obtained pigment were studied.
