Chromium diboride (CrB₂) is a ceramic compound belonging to the transition metal boride family, combining chromium with boron in a hard, refractory phase. It is used in wear-resistant coatings, cutting tool materials, and high-temperature structural applications where extreme hardness and thermal stability are required. CrB₂ is valued as an alternative to traditional hard ceramics and cermets because of its combination of hardness and relative toughness, making it suitable for abrasive environments where conventional materials degrade rapidly.
