Oxidation inhibitor

Abstract

An oxidation inhibitor comprising; (A) 10 to 200 parts by weight of at least one selected from the group consisting of Silica powder Kaoline Magnesia powder MgO-Cr.sub.2 O.sub.3 refractories Mg-SiO.sub.2 refractories, and Mica (B) 10 to 200 parts by weight of silicic anhydride (SiO.sub.2), (C) 10 to 200 parts by weight of at least one selected from the group consisting of Cr, Al, Ti, Nb, Ni and Cu in the powder form, (D) 5 to 50 parts by weight of at least one selected from the group consisting of colloidal silica and alumina sol, and (E) 1 to 20 parts by weight of water-soluble resin, wherein the ratio of the metal powder to the total solid components is within a range defined by the following formula: ##EQU1## (the total solid components is the sum of (A)+(B)+(C)+(solid component of D)+(E)).
