Abstract:

Obtaining dissociated zircon (a mixture of associated dioxides of zirconium and silicon (ZrO2, SiO2) by sintering ZrSiO4 with MgO and the subsequent leaching of the forming pitch by concentrated hydrochloric acid is studied. The mechanism of sintering of the ZrSiO4 + MgO mixture is established based on laboratory investigations. The optimal parameters of the process (the molar ratio of components and the temperature and duration of heating at the final temperature) for the maximal transformation of zircon into zirconium dioxide are determined.
