Title

Oxidation Behavior Of Zrb 2-Sic-Tac Ceramics

Abstract

ZrB 2-SiC-TaC ceramics with different content of TaC were prepared by hot-pressing at 1800°C in vacuum environment. The oxidation behavior of these ceramics was studied in the temperature range of 1200°C-1500°C in air. It was found that low concentration of TaC (10 vol%) deteriorated the oxidation resistance of ZrB 2-SiC, while high concentration of TaC (30 vol%) significantly improved the oxidation resistance of the ceramics. Reoxidation experiments indicated that the metallic species (tantalum and/or silicon) diffusing out of the materials into the oxides was initially involved in the controlling process. © 2011 The American Ceramic Society.
