Abstract
Aluminum smelters produce pure aluminum in reduction cells by the Hall-Héroult process, however, aluminum is usually supplied as a variety of alloys to their customers. The alloys are produced in the casthouse, as desired alloying elements are added to the primary aluminum from the potroom before casting. In this work the concept of producing titanium master alloys directly in the aluminum reduction cells is discussed, by feeding titanium oxide to the electrolyte, along with the alumina raw material. The results in this paper are obtained by running electrolysis experiments in a laboratory cell, and the current efficiency for the alloy deposition is estimated. Similar results for aluminum–silicon and aluminum-manganese alloys are reported in a different paper.
