ceramic

· JVASP-9714· YNbO4

YNbO4 is a rare-earth niobate ceramic compound composed of yttrium, niobium, and oxygen, belonging to the family of mixed-metal oxides with potential high-temperature and dielectric applications. This material is primarily investigated in research contexts for its thermal stability and structural properties, making it a candidate for advanced ceramic applications where conventional oxides may be insufficient. Its notable characteristics position it within the broader class of refractory ceramics and functional ceramics used in high-temperature environments and electronic devices.
