· VB

Vanadium Boride (VB) is a ceramic intermetallic compound combining vanadium and boron, belonging to the refractory metal boride family. It is primarily of research and specialized industrial interest, valued for applications requiring extreme hardness, high melting point, and chemical resistance in harsh environments. VB appears in cutting tool coatings, wear-resistant surfaces, and high-temperature structural applications where conventional metals fail, though it remains less common than established alternatives like tungsten carbide or titanium boride due to processing challenges and cost.
