摘要	Thermochemical reactions between rare earth (RE) monosilicates (RE2SiO5) and molten calcium-magnesium-aluminosilicate (CMAS) at 1300 degrees C were investigated. Some RE2SiO5 (RE = Tb, Dy, and Ho) dissolve readily into CMAS melts and thereby, crystalline Ca2RE8(SiO4)(6)O-2 reprecipitate. Other RE2SiO5 (RE = Tm, Yb, and Lu) resist CMAS attack, and a continuous layer of Ca2RE8(SiO4)(6)O-2 establishes at the interface. The recession of RE2SiO5 is related to RE ionic radius. RE2SiO5 with small RE ionic radius exhibits good CMAS corrosion resistance due to its low reactivity with CMAS. This result is consistent with the same trend of difference in the optical basicity of RE2SiO5/CMAS.
