ZrCaOFN

ZrCaOFN is an oxynitride ceramic compound containing zirconium, calcium, oxygen, and nitrogen phases, representing an emerging materials class that combines the thermal stability and hardness typical of zirconium-based ceramics with the enhanced mechanical properties and oxidation resistance that nitrogen incorporation can provide. This material family is primarily in the research and development stage, investigated for high-temperature structural applications where improved fracture toughness and resistance to thermal shock are needed beyond conventional oxides. The addition of nitrogen to zirconium-calcium oxide systems is motivated by potential use in aerospace, high-temperature tooling, and advanced thermal barrier applications where material performance at elevated temperatures and resistance to oxidative degradation are critical design drivers.
