Abstract
A method for the production of an intermetallic compound (M1Z) involves treating a solid precursor material comprising three or more species, including first and second metal or metalloid species (M1, Z) and a non-metal species (X), by electro-deoxidation in contact with a melt comprising a fused salt (M2Y) under conditions whereby the non-metal species dissolves in the melt. The first and second metal or metalloid species form an intermetallic compound. The method is performed in a cell comprising a cathode of the precursor material (2), which is immersed in a melt (8) contained in a crucible (6) for electro-deoxidation.
