Zirconium boride is a hard, refractory ceramic compound with exceptional thermal stability, high melting point, and electrical conductivity, making it ideal for cutting tools, wear-resistant coatings, and high-temperature applications. Industrial buyers use it as a refractory for aircraft and rocket parts and molten-metal contact, a diffusion barrier in semiconductor fabrication, and a high-temperature electrical conductor. It has a CAS number of 12045-64-6, a molecular formula of B₂Zr, and a molecular weight of 112.85 g/mol. Store at ambient conditions with a signal word of *Warning* for safety handling. Molekula supplies Zirconium boride from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
