WRuON2

WRuON2 is a ceramic compound containing tungsten, ruthenium, oxygen, and nitrogen—a mixed-metal oxynitride material belonging to the refractory ceramic family. This material is primarily of research interest for high-temperature and wear-resistant applications, leveraging the exceptional hardness and thermal stability of tungsten-ruthenium-based systems combined with nitride strengthening. The oxynitride composition positions it as a candidate for extreme environments where conventional oxides or nitrides alone may fall short, though it remains largely experimental; engineers would consider it for specialized applications requiring simultaneous resistance to oxidation, thermal shock, and mechanical wear at elevated temperatures.
