HfMoO2N

HfMoO₂N is an experimental oxynitride ceramic combining hafnium, molybdenum, oxygen, and nitrogen phases. This compound belongs to the family of refractory oxynitrides and is primarily investigated in research settings for high-temperature structural applications where conventional oxides or nitrides fall short. The material's appeal lies in its potential to combine the oxidation resistance of oxides with the mechanical strength and thermal stability of nitrides, making it a candidate for extreme-environment engineering where thermal shock resistance, chemical durability, and mechanical retention at elevated temperatures are critical.
