The exposed ceramics included different SiC grades (solid state-sintered, liquid phase-sintered, and silicon-infiltrated) and MAX phase-based materials (Maxthal{\textregistered} 211 & 312 (nominally, Ti2AlC & Ti3 SiC2, respectively), Cr2AlC, Nb4AlC3, (Nb,Zr)4AlC3, and a cermet comprising 40 vol% Fe and 60 vol% (Nb,Zr)4AlC3). All SiC grades were chemically stable in the molten salt, whereas all Nb-containing MAX phase ceramics were severely oxidized. Comparing the two Maxthal{\textregistered} grades showed that the 312 was chemically more stable than the 211, and both grades formed a Na-based oxide scale. Interestingly, Cr2AlC showed practically no interaction with the molten salt during the performed exposure, forming a stable, sub-micrometre-thick Cr7C3 scale.

The exposed ceramics included different SiC grades (solid state-sintered, liquid phase-sintered, and silicon-infiltrated) and MAX phase-based materials (Maxthal® 211 & 312 (nominally, Ti2AlC & Ti3 SiC2, respectively), Cr2AlC, Nb4AlC3, (Nb,Zr)4AlC3, and a cermet comprising 40 vol% Fe and 60 vol% (Nb,Zr)4AlC3). All SiC grades were chemically stable in the molten salt, whereas all Nb-containing MAX phase ceramics were severely oxidized. Comparing the two Maxthal® grades showed that the 312 was chemically more stable than the 211, and both grades formed a Na-based oxide scale.
