Eric, They need to dissolve it into a material that allows the titamium to form ions, much like salt and water allows you to electrolyze salt to chlorine and sodium(hydroxide) The Hall process does that with Al2O3 in fluorite melt. Since the fluorite is more electropositive the aluminium plates out first as melted aluminium. The titanium ions are attracted to the cathode and accept electrons to become pure metal and there is nothing right there to react with it(the oxygen having gone to the other electrode and it bubbles off) With these strongly bound water insoluble materials, Al2O3 and TiO2 it takes quite some doing to get them into an ionic solution. This all takes place in a molten cell at almost 1800 C,(I am not sure of this temp) I think the Hall cells are also just under 1000 C. The slurry idea will not work as there is no ionic solution. Bill
