ABSTRACT:
Disclosed is a method of insulating ferromagnetic amorphous metal strip by coating the strip with a composition of about 3 to about 32% of a metal alkoxide having a general formula of M(OR).sub.n, where M is an alkoxide forming metal, R is alkyl, and n is the valence of the M, about 56 to about 96% of a solvent for the metal alkoxide, about 1 to about 12% water, and about 0.001 to about 0.01% of an acid. The coated strip is heated at a temperature above the temperature at which the metal alkoxide hydrolizes and polymerizes and the water and solvent evaporate, and below the temperature at which the amorphous metal crystallizes. Also disclosed is ferromagnetic amorphous metal strip insulated with a coating of glass that is about 0.001 to about 0.02 mils thick.
