Abstract

ZrB2-SiC composites were prepared by arc melting using ZrB 2 and β-SiC powders as raw materials and their oxidation behavior were investigated. The eutectic composition of the ZrB2-SiC system was ZrB2-58.5mol%SiC and the melting point temperature was about 2570 K. At 1673 K mass gain was observed in the oxidation of ZrB 2-SiC eutectic composition and the mass gain rate increased with decreasing Ptot. The oxide scale consisted of an amorphous SiO 2 layer, a ZrO2-SiO2 eutectic-like layer and a Si-deficient layer.
