Building phase diagrams for Cu-As-(Ni, Sb) alloys
Sulfosalt minerals, from which copper (Cu) is mined, are characterised by high concentrations of arsenic (As), nickel (Ni) and antimony (Sb). However, the properties of Cu-As-(Ni, Sb)-based alloys are poorly understood. As no phase diagrams of such ternary alloys exist, their material characteristics remain widely unknown. Funded by the Marie Skłodowska-Curie Actions programme, the ASCUNISB project will focus on the physico-chemical properties of Cu mined from sulfosalt minerals. The project will build phase diagrams for Cu-As-(Ni, Sb) alloys by investigating each alloy phase and identifying unknown phases. ASCUNISB will also create a base for new applications, reduce economic and environmental costs, and deliver a database to address urgent research questions by assessing the earliest metal technologies c. 2300 BCE.
