Abstract Scope |
This paper reports a study on the electrochemical synthesis of an aluminium-titanium alloy in-situ during aluminium reduction in fluoride-based melts. Experiments were carried out in a controlled laboratory cell with a carbon anode and a liquid aluminium cathode using industrial standards for temperature, cryolite ratio, and current density. TiO2 was added as a raw material along with alumina. Bath samples were collected regularly and analyzed with ICP-MS to estimate the co-deposition rate of titanium during the experiment. Apparent current efficiencies were recorded, and analysis of deposit was carried out by ICP-MS to complete the material balance in order to calculate the real current efficiencies. The content of titanium was varied up to 1.0 wt.% and alumina concentration in the bath was below saturation. |
