Vanadium diboride (VB₂) is a refractory ceramic compound belonging to the transition metal boride family, valued for its exceptional hardness and thermal stability at elevated temperatures. It is used primarily in cutting tool coatings, wear-resistant components, and specialized high-temperature applications where conventional materials fail; its main advantage over competing ceramics is superior hardness combined with reasonable fracture toughness, making it particularly attractive for precision machining and abrasive environments where tool life and cost-per-part matter significantly.
