P2Pt is an intermetallic compound in the platinum-phosphorus system, combining platinum's exceptional corrosion resistance and thermal stability with phosphorus to create a material with modified mechanical and chemical properties. This compound is primarily of research and specialized industrial interest, used in catalysis, electrical contacts, and high-temperature applications where platinum's intrinsic nobility must be balanced with improved hardness or specific electronic behavior. Engineers would consider P2Pt when standard platinum is too soft or costly, or when the intermetallic's altered electronic structure offers advantages in electrochemistry or surface reactivity over pure platinum.
