BeAu3
metal· JVASP-37809· BeAu3
BeAu₃ is an intermetallic compound composed of beryllium and gold, belonging to the class of precious metal intermetallics. This is a research-stage material with limited commercial deployment; it represents an experimental composition within the beryllium-gold phase diagram studied for its potential in specialized applications requiring combined properties of both constituents. The material is notable for its extreme density and potential for applications where gold's chemical inertness and beryllium's lightweight character might be simultaneously beneficial, though practical use remains constrained by beryllium's toxicity hazards, high cost, and challenging manufacturing requirements.
