摘要	(Er0.25Tm0.25Yb0.25Lu0.25)(2)Si2O7 with excellent CMAS corrosion resistance has been designed for the application of environmental barrier coating. The mechanisms governing the enhancement was disclosed through experi-mental investigations of the bulk sample corroded by highly corrosive CMAS melts at 1500 ? for 4 and 50 h. The results demonstrate the synergistic effects of multi rare earth species for the improved CMAS resistance of RE-disilicates. Inert elements (Lu/Yb) benefit the maintaining of phase stability of the disilicate; and simulta-neously, active elements (Er/Tm) promote the precipitation of precipitated phase and reduce the corrosion ac-tivity by promptly change the composition of CMAS.
