Abstract SiO 2 /ZrO 2 -SiO 2 composites were fabricated by the sol-gel process, and their high-temperature flexural properties were explored. The oxidation behavior at 1200 °C and 1500 °C was also investigated. At high temperature, the composites showed typical brittle fracture. SiO 2 /ZrO 2 -SiO 2 composites had higher flexural strength and elastic modulus at high temperature than SiO 2 /SiO 2 composites. SiO 2 /ZrO 2 -SiO 2 composites, which were fabricated by sol-gel process, showed a higher high temperature lifetime.
