摘要：

Phase relations in the SiC-Al2O3-Y2O3 system were determined by phase analyses of the solid-state reacted samples from powder mixtures of SiC, Al2O3 and Y2O3. The phase diagram at 1700 degrees C of the ternary system was presented. SiC was compatible with each of the three yttrium aluminates of Y4Al2O9 (YAM), YAlO3 (YAP) and Y3Al5O12 (YAG). Stability of the YAP phase and possible effect of the SiO2 impurities on the phase relations in the system were discussed. (C) 2015 Elsevier B.V. All rights reserved.
