Abstract

See full text

A coating liquid includes aluminum phosphate, a nonionic surfactant, and water and/or water-soluble solvent that dissolves or disperses the aluminum phosphate and the nonionic surfactant. An amount of the nonionic surfactant is preferably 1 vol % or more and 10 vol % or less. The nonionic surfactant is preferably at least one selected from the group consisting of ester, ether, alkylglycoside, octylphenol ethoxylate, pyrrolidone, and polyhydric alcohol. Applying such a coating liquid to a surface of a thermoelectric member, and drying and firing the coating liquid enables formation of a dense antioxidant film containing aluminum phosphate on the surface of the thermoelectric member.
