Abstract

Process for producing oriented silicon-iron sheet material, characterized in that a magnetic sheet material provided with silica is treated above and below the surfaces of the material, with an annealing separator comprising a glass-forming substance and a chosen material between the class consisting of sodium and potassium hydroxides and sulfides, said laminar material being subjected to a heat treatment at a temperature sufficient to cause the melting of part of said glass forming substance with silica on the surface of said laminar material, in the presence of the said alkali metal compounds are formed, thus forming on the surfaces of said material a thin and substantially uniform film of an easily separable material and of the surfaces of said material, said film separating from the surfaces of the sheet material.
