metal

· JVASP-14049· KAuBr4

KAuBr4 is an intermetallic compound containing potassium, gold, and bromine, belonging to the family of metal halide complexes. This material is primarily of research and academic interest rather than established industrial production, with potential applications in solid-state chemistry, materials synthesis, and specialized electronic or optical device development. Gold-containing halide compounds like this are investigated for their unique electronic properties and potential use in advanced materials research, though practical engineering applications remain limited compared to conventional metallic alloys.
