Abstract

Thermal destruction of indium and dysprosium hydroxides coprecipitated from solutions of their nitrate and chloride salts with ammonia was investigated by DTA/TG, XRD and MS methods. The features of these processes were revealed in solutions of different nature. It is shown that the method of thermal decomposition of mixed indium and dysprosium hydroxides coprecipitated from the solution of their chloride salts is environmentally appropriate and economically viable. The size of the coprecipitated hydroxide particles of indium oxide produced through thermal destruction at up to 500 °C (13 nm) allows us to recommend this method for production of nanodispersed mixed oxides of indium and dysprosium.
