In this paper, the preparation of a GdSiO4+Mullite coating by a slurry dip process is described. The slurry was optimized in
terms of solid loading, solvent type and the chemical as dispersant and/or binder, and the process was determined based on
the surface quality by SEM examination. The results showed that a slurry using ethanol as solvent, polyvinyl butyral (PVB)
as both dispersant and binder together with a relatively high ceramic loading contributed to the successful deposition of a
GdSiO4+Mullite coating on SiC.
