· As2Pt

As₂Pt is an intermetallic compound combining arsenic and platinum, belonging to the family of noble metal intermetallics. This is primarily a research and specialized material rather than a commodity engineering metal, studied for its unique combination of high density and elastic properties derived from platinum's inherent nobility and arsenic's alloying effects. Potential applications are concentrated in high-performance research contexts such as advanced catalysis, wear-resistant coatings, and specialized electronics where platinum's corrosion resistance and arsenic's metalloid properties can be leveraged; however, arsenic toxicity concerns and cost constraints severely limit industrial adoption compared to conventional platinum alloys or nickel-based superalloys.
