Description

Zirconium Diboride (ZrB₂) is an advanced ultra-high-temperature ceramic (UHTC) material renowned for its exceptional thermal stability, mechanical strength, and resistance to oxidation. With a molecular formula of B₂Zr and CAS number 12045-64-6, this refractory compound exhibits a unique combination of properties, including high melting point (~3245°C), excellent thermal conductivity, and superior hardness, making it ideal for extreme environments. Zirconium diboride is synthesized via powder metallurgy or chemical vapor deposition (CVD) to achieve high purity (>99%) and controlled particle size distributions. Its hexagonal crystal structure contributes to its remarkable wear resistance and chemical inertness, even in corrosive atmospheres. Applications span aerospace, nuclear reactors, and cutting-edge metallurgical processes. Available as fine powder, sintered pellets, or custom forms, our ZrB₂ is rigorously tested for phase purity (XRD), density (Archimedes’ method), and particle morphology (SEM).

Application

Zirconium diboride is widely used in aerospace thermal protection systems (TPS) due to its ability to withstand temperatures exceeding 3000°C. It serves as a critical component in hypersonic vehicle leading edges and rocket propulsion nozzles. In metallurgy, ZrB₂ enhances the wear resistance of composites and acts as a grain refiner in aluminum alloys. The material also finds niche applications in neutron absorption for nuclear control rods and as an electrode in high-temperature electrochemical cells.
