ZrSiO2N

ZrSiO₂N is an oxynitride ceramic compound combining zirconium, silicon, oxygen, and nitrogen phases, developed primarily as a research material for advanced high-temperature and wear-resistant applications. This material class is of interest in aerospace and tribological engineering where exceptional thermal stability, hardness, and oxidation resistance are required; it represents an evolution beyond traditional silicates and nitrides by leveraging the combined benefits of zirconia's toughness and silicon nitride's thermal shock resistance. The material remains largely in research and development stages, with potential for applications demanding simultaneous improvements in fracture toughness and creep resistance at elevated temperatures.
