· Ba1 Au5

Ba1Au5 is an intermetallic compound composed of barium and gold in a 1:5 stoichiometric ratio, belonging to the class of metal-metal intermetallics with potential semiconductor behavior. This material is primarily of research interest rather than established industrial production, as it represents an uncommon combination in the barium-gold phase diagram; such compounds are studied for their potential electronic and structural properties in specialized applications. The barium-gold system has been explored in academic settings for investigating novel electronic structures and phase relationships, though practical engineering applications remain limited compared to more conventional semiconductors or intermetallic systems.
