文摘

The present work determined the phase relations in Si-Al-M-O-C (M = Zr, Mg) systems, involving SiC-Al₂O₃-ZrO₂, SiC-Al₂O₃-MgO, SiC-SiO₂-Al₂O₃-ZrO₂ and SiC-SiO₂-Al₂O₃-MgO systems by XRD phase analyses of the solid-state reacted samples from powder mixtures of SiC, Al₂O₃, ZrO₂, MgO and SiO₂. Within these systems, SiC was respectively compatible with other neighboring phases, forming a set of four-phase compatibility tetrahedrons. The subsolidus phase diagrams of the SiC-SiO₂-Al₂O₃-ZrO₂ and SiC-SiO₂-Al₂O₃-MgO quaternary systems were presented.
