Abstract

Раскрыт процесс электрохимического восстановления оксида титана в твердом состоянии в электролизере, который включает в себя анод, катод, расплавленный электролит на основе CaCl, содержащий СаО, и загружаемый титанооксидный материал в контакте с расплавленным электролитом. Данный процесс характеризуется регулированием процесса путем регулирования концентрации СаО в электролите.The process of electrochemical reduction of titanium oxide in a solid state in an electrolyzer is disclosed, which includes an anode, a cathode, a molten CaCl-based electrolyte containing CaO, and a charged titanium oxide material in contact with molten electrolyte. This process is characterized by regulation of the process by controlling the concentration of CaO in the electrolyte.
