· JVASP-49227· K3Nb3B2O12

K3Nb3B2O12 is an advanced ceramic compound belonging to the niobium borate family, combining potassium, niobium, boron, and oxygen into a dense crystalline structure. This material is primarily of research and development interest for applications requiring high rigidity and thermal stability, though industrial deployment remains limited. The niobium-borate ceramic family shows promise in electronic, optical, and structural applications where conventional oxides fall short, particularly in high-temperature environments or as functional ceramics in microelectronics and photonics.
