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.

Abstract: A precursor powder comprising a metal compound is formed into a sample for electro-deoxidation, for example by slip-casting. The sample is then immersed in a melt comprising a molten salt and a cathodic potential applied to remove non-metal species from the precursor powder by electro-deoxidation and dissolution in the melt. This typically forms a metallic sample which can be fragmented to form a metallic powder. In a second aspect of the invention a powdered feed material is formed into a shaped precursor and more extensive electro-deoxidation carried out so as to form a near-net shaped product.

Abstract: Electronically conductive composites of electronically conductive polymers and carbon nanotubes are formed by electrochemical or gel polymerisation of monomer in a carbon nanotube suspension. Electrical energy storage devices are produced from carbon nanotube/electronically conductive polymer composites.
