Early-stage oxidation behavior at high temperatures of SiSiC cellular architectures in a porous burner

Sophia Haussener, Ehsan Rezaei, Alberto Ortona

Early stage oxidation behavior of SiSiC cellular lattices with different cell types was studied at 1400 degrees C in two different environments: a porous burner and an electric furnace with stagnant air. Oxidation and silicon alloy bead formation were obse ...
