· JVASP-56724· Ca5WN4O2

Ca5WN4O2 is a ceramic compound combining calcium, tungsten, nitrogen, and oxygen—a rare earth oxynitride belonging to the broader family of refractory and high-performance ceramics. This material is primarily of research and developmental interest rather than established industrial production, with potential applications in extreme-temperature environments, wear-resistant coatings, and advanced structural ceramics where thermal stability and hardness are critical.
