Chromium Boride Powder (Cr₅B₃)

Chromium Boride Powder (Cr₅B₃) is a refractory intermetallic compound valued for its outstanding hardness, high melting point, and resistance to chemical attack. With a tetragonal crystal structure, Cr₅B₃ offers exceptional wear resistance and maintains stability under extreme thermal and mechanical stresses, making it ideal for applications in tooling, wear coatings, and advanced ceramics. Its high-temperature oxidation resistance supports its use in aerospace, defense, and heavy manufacturing industries. Notable applications include reinforcement in metal–matrix composites, protective coatings for high-speed cutting tools, and mould materials for precision casting in aggressive environments. In research, Cr₅B₃ serves as a model system for studying boride phase formation, sintering behavior, and microstructural optimization in ultra-high-temperature materials. The combination of mechanical resilience, chemical inertness, and thermal stability positions Cr₅B₃ as a critical material for both industrial and scientific advancements where extreme performance is required.
