Abstract

Calcium hexaboride has high melting point (2372K), high hardness (27 GPa), low density (2.45 g/cm3), high Young's modulus (379 GPa) and low thermal expansion. This material has capability for using in composite and as an antioxidant in Oxide-graphite refractories. Synthesis of calcium hexaboride by different processes as hydrothermal, solid state and combustion synthesis are done. CaB6 as an antioxidant in MgO-C refractories can reduce the oxidation of graphite. In this study synthesis and application of CaB6 as an antioxidant are investigated.
