ceramic

· JVASP-13300· Zr7N4O8

Zr7N4O8 is an oxynitride ceramic compound combining zirconium, nitrogen, and oxygen phases, representing a research-stage material in the zirconium ceramic family. This composition occupies a space between traditional zirconium oxides and zirconium nitrides, potentially offering tailored mechanical and thermal properties for high-performance applications. The material is primarily of academic and developmental interest, with potential applications in advanced thermal barriers, wear-resistant coatings, or high-temperature structural components where the combined oxynitride phases may provide improved performance compared to single-phase alternatives.
