Niobium Boride is a kind of gray crystalline powder. It has the characteristics of high melting point, high hardness, good electrical and thermal conductivity, resistance to molten metal corrosion, and superconductivity. 

NbB can be used to make ultra-high temperature structural materials and superconducting materials with important applications in extreme environments like ultra-high temperature, metal smelting, etc. Niobium Boride is a highly covalent refractory ceramic material with a Orthorhombic crystal structure.
