P4Ru

ceramic

· JVASP-12729· P4Ru

P4Ru is a ceramic compound in the phosphide family, combining phosphorus with ruthenium. This intermetallic ceramic material is primarily of research interest for advanced applications requiring high stiffness and thermal stability, as ruthenium-based compounds offer excellent corrosion resistance and high-temperature performance characteristics typical of noble metal ceramics.
