Feasibility study of ZrSiO4 as matrix and fiber interphase of SiC/SiC composite

ZrSiO 4 demonstrates applicability as the SiC/SiC interphase. Via a non-hydrolyzed sol-gel method, the pyrolysis product, synthesis condition, and the formation effectiveness of the ZrSiO 4 coating on SiC fibers were investigated. Mini-SiC/SiC composites with two layers of ZrSiO 4 interface coatings were oxidized to preliminarily verify their oxidation resistance effect.
