Isothermal Oxidation Behavior of AlN-TiB₂ Ceramics Synthesized by SHS-HIP

Abstract:

sothermal oxidation behavior of the AlN-TiB₂ conductive ceramics prepared by self-propagating high-temperature synthesis and hot isostatic pressing (SHS-HIP) was evaluated in a temperature range from 900 to 1400 °C for exposure times from 1 to 16 h in air. The oxidation experimental results show that the conductive ceramics have a good oxidation resistance below 1200 °C. The oxidation products on the sample surfaces are mainly composed of Al₂TiO₅, TiO₂ and aluminum borate phases.
