Be1 Au3
semiconductor· Be1 Au3
Be₁Au₃ is an intermetallic compound combining beryllium and gold in a 1:3 atomic ratio, belonging to the class of metallic intermetallics. This material exists primarily in research and specialized contexts rather than high-volume industrial production, as it combines the low density of beryllium with gold's nobility and thermal properties. Interest in beryllium-gold systems stems from their potential for high-temperature structural applications, wear resistance, and biocompatibility in niche applications, though beryllium's toxicity in powder form and high material cost severely limit practical deployment.
