Abstract
In a method for manufacturing a member for use in a molten metal bath, a sealing solution is applied on a coating formed of oxide system ceramics formed on an outermost surface of a substrate. The sealing solution includes an inorganic colloid compound solution containing an inorganic colloid having a grain diameter in a range of 5-50 nanometers in an amount of 5-50 weight percent, and an inorganic binder. The inorganic binder is mixed at a weight ratio of 0.3-3.0 with respect to a weight of 1.0 of the inorganic colloid. The oxide system ceramic formed on the outermost surface of the substrate is an oxide containing 5% or more of a composite oxide comprising (a) at least one of Al, Ti, V, Cr, Fe, Co, Rh, In and rare earths, which are trivalent metal elements, and (b) at least one rare earth different from that used in (a). The sealing solution on the coating after permeation is then baked.
