· JVASP-18950· RhO2

RhO₂ (rhodium dioxide) is a ceramic oxide compound combining the precious metal rhodium with oxygen, belonging to the family of transition metal oxides. It is valued for its exceptional chemical stability, high melting point, and catalytic properties, making it suitable for demanding high-temperature and corrosive environments where conventional ceramics or metals would fail. This material is primarily used in specialized industrial catalysis, electrochemistry, and high-temperature sensor applications, where its resistance to oxidation and chemical attack justifies the cost premium of rhodium-based compounds.
