ZrHfO2N

ZrHfO2N is a ceramic compound combining zirconium, hafnium, oxygen, and nitrogen—a refractory oxynitride material engineered for extreme thermal and chemical environments. This material belongs to the family of high-entropy or multi-principal-element ceramics and is primarily of research and emerging industrial interest for applications requiring exceptional thermal stability, oxidation resistance, and mechanical retention at very high temperatures. It offers potential advantages over conventional refractory oxides in aerospace, thermal barrier, and nuclear applications where cost-effective alternatives to pure hafnia or stabilized zirconia are sought.
