The wetting reaction between LiF and BaTiO 3 was studied by examining the reaction products on the LiF‐wetted surface of BaTiO 3 . A reduction reaction occurred between the melt of LiF and BaTiO 3 , causing the formation of LiTiO 2 and volatilization of fluorine. The wetted surface consisted of spherical particles of LiTiO 2 and eutectically decomposed phases of BaLiF 3 and LiTiO 2 . The formation of LiTiO 2 was repressed by the addition of excess BaO in the melt of LiF, and a well‐spread film was formed on the surface of BaTiO 3 . The wetting between BaLiF 3 and BaTiO 3 was also examined. The reaction of forming LiTiO 2 did not occur, and a mosaic film was formed on the surface of BaTiO 3 .
