The presentation provides a review of coloured gold, platinum and palladium intermetallic compounds, and discusses the models that were developed to obtain these materials. These compounds have a crystal structure of high symmetry, ensuring distinct electron band structures. Various examples of coloured gold, platinum and palladium intermetallic compounds are provided. More ler in-depth discussion is provided on purple gold (AuAl2) and yellow platinum – aluminium (PtAl2) as well as the purplish – pink palladium – indium (PdIn) compound. Precious metal intermetallic compounds are used in jewellery and provide a new dimension to design. Click HERE for more information.
