Abstract

The electrochemical production of an aluminium-titanium alloy in situ during aluminium reduction in fluoride-based melts was investigated. Experiments were carried out in a laboratory cell at 0.9 A/cm² and temperatures 960 and 970 °C. 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 and calculate the real current efficiencies. The content of titanium was varied up to 1 wt% and alumina concentration in the bath was below saturation.
