报告内容简介：The direct electrochemical reduction of solid titanium dioxide in a chloride melt is an attractive method for the production of titanium metal. It has been estimated that this type of electrolytic approach may reduce the costs of producing titanium sponge by more than half, with the additional benefit of a smaller environmental footprint. The process utilises a consumable carbon anode which releases a mixture of CO2 and CO gas during electrolysis, but suffers from low current efficiency due to the occurrence of parasitic side reactions involving carbon. The replacement of the carbon anode with a cheap, robust inert anode offers numerous benefits that include: elimination of carbon dioxide emissions; more efficient cell operation; opportunity for three–dimensional electrode configurations and reduced electrode costs. The talk will discuss the challenges of developing a long-lived inert anode material, and report experimental studies for a wide variety of metals, alloys and conductive ceramics.
