Niobium boride is a gray hexagonal crystal, mainly used as fine ceramic raw materials and superconducting materials.
Among the superconducting materials, only NbB has higher superconducting transition temperature performance. At the same time, Niobium boride is the raw material of gold brazing material. After the brazing material is brazed with the refractory metal NbN, the wettability and spreadability are excellent solder fluidity, strong filling capacity, and excellent high temperature strength of the weld.
