Ruthenium tetroxide (RuO₄) is a volatile oxidizing ceramic compound composed of ruthenium in its highest oxidation state, typically encountered as a research material or specialized oxidizing agent rather than a structural ceramic. While not commonly used as an engineering material in bulk form due to its instability and toxicity, RuO₄ appears in electrochemistry, catalysis research, and specialized oxidation applications where its strong oxidizing properties are exploited. Engineers encounter this compound primarily in laboratory and industrial process chemistry rather than in load-bearing or thermal applications.
