· Nb5Sb4

Nb₅Sb₄ is an intermetallic compound composed of niobium and antimony, representing a member of the refractory metal-based intermetallic family. This material is primarily of research and development interest rather than established in high-volume industrial production, with investigation focused on understanding its mechanical and thermal properties for potential high-temperature structural applications. The niobium-antimony system is studied as a candidate for advanced aerospace and energy applications where lightweight, high-strength materials with thermal stability are required.
