초록
In this study, sintered silicates such as Yb2SiO5, Gd2SiO5, mullite, Ba-Sr-Al silicate (BSAS), and Y2SiO5 are fabricated andcharacterized. The oxide silicates are considered environmental barrier coating materials for protecting Si-based ceramicsubstrates in gas turbine applications from oxidation and corrosion resulting from reactions with water vapor at hightemperature. Microstructure observation, phase analysis, and mechanical properties measurements indicate that the heattreatedYb2SiO5 material includes crystalline phases, and it shows a relatively dense microstructure with improved mechanicalproperties.
