abstract = {Rare earth silicate environmental barrier coatings (EBCs)
are state of the art for protecting SiC ceramic matrix
composites (CMCs) against corrosive media. The interaction
of four pure rare earth silicate EBC materials Yb2SiO5,
Yb2Si2O7, Y2SiO5, Y2Si2O7 and three ytterbium silicate
mixtures with molten calcium‐magnesium‐aluminosilicate
(CMAS) were studied at high temperature (1400°C). The
samples were characterized by SEM and XRD in order to
evaluate the recession of the different materials after a
reaction time of 8 hours. Additionally, the coefficient of
thermal expansion (CTE) was determined to evaluate the
suitability of Yb silicate mixtures as EBC materials for SiC
CMCs. Results show that monosilicates exhibit a lower
recession in contact with CMAS than their disilicate
counterparts. The recession of the ytterbium silicates is
far lower than the recession of the yttrium silicates under
CMAS attack. Investigation of the ytterbium silicate
mixtures exposes their superior resistance to CMAS, which is
even higher than the resistance of the pure monosilicate.
Also their decreased CTE suggests they will display better
performance than the pure monosilicate.},
