1. A method for enhancing the resistance of a porous solid material to the infiltration and penetration of a molten salt, the method comprising:
providing a porous solid material having an exterior surface adapted to contact the molten salt and pores having entrances at the exterior surface; and
introducing into the pores of the porous solid material a non-wetted solid that is not infiltrated or penetrated by the molten salt;
wherein the non-wetted solid is introduced into the pores of the porous solid material by the infiltration of a fluid precursor material to the non-wetted solid into the pores of the porous solid material, followed by conversion of the fluid precursor material into the non-wetted solid within the pores of the porous solid material; and
wherein the fluid precursor material to the non-wetted solid comprises a vapor precursor material and the conversion of the vapor precursor material to the non-wetted solid is conducted by one or more of condensation of the vapor precursor material onto the internal surfaces of the porous solid material and a thermal treatment to allow the vapor precursor material to undergo a chemical reaction.
