Synthesis and high-temperature oxidation of a polymer-derived Mo-SiN based ceramic composite

摘要

Si3N4 ceramics strengthened with molybdenum silicides seem to be potential candidates for (ultra-)high temperature applications. While Mo5Si3 exhibits a higher melting point and a better creep resistance than MoSi2, its oxidation resistance is inferior due to accelerated pest oxidation at 700 degrees C in air.
