Abstract
Methods, materials systems, and devices for inhibiting the infiltration and penetration of molten salts into solid materials, including porous materials at temperatures above the solidus temperature of the molten salt. The methods, materials systems, and devices utilize a non-wetted solid that is introduced into pores having entrances at an exterior surface of a porous solid material adapted to contact the molten salt.
Claims10
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.
