NbBO4

ceramic

· NbBO4

NbBO4 is an inorganic ceramic compound composed of niobium and boron oxides, belonging to the family of mixed-metal borate ceramics. This material is primarily of research and developmental interest for high-temperature and optical applications due to its refractory characteristics and potential ferroelectric or nonlinear optical properties. Engineering interest centers on thermal barrier coatings, advanced optical devices, and high-temperature structural applications where conventional oxides reach performance limits.
