ceramic

· P2Ru

P2Ru is a ceramic compound in the ruthenium phosphide family, combining phosphorus and ruthenium in a stoichiometric 2:1 ratio. This material belongs to a class of metal phosphide ceramics that have attracted research attention for their potential as electrocatalysts, wear-resistant coatings, and high-temperature structural materials. While not widely established in mainstream engineering applications, P2Ru and related ruthenium phosphides are being investigated as alternatives to precious-metal catalysts and as components in corrosion-resistant systems due to ruthenium's inherent chemical stability.
