In5CuSe8

In₅CuSe₈ is a ternary intermetallic compound combining indium, copper, and selenium, belonging to the family of metal chalcogenides. This material is primarily of research interest rather than established industrial production, with investigation focused on its potential as a semiconductor or thermoelectric material given its mixed-metal composition and moderate density. Engineers would consider this compound for emerging applications requiring specific electronic or thermal transport properties, though it remains largely in the development phase compared to more established commercial alternatives.
