ABSTRACT:
By adding an appropriate amount, 1 to 12 weight percent, based on the amount of magnesium oxide present and Loss On Ignition values of powdered magnesium metal to the magnesium oxide aqueous slurry composition used to make a separating-agent composition in the making of grain-oriented silicon electrical steel, there are obtained composition, an article, and a method characterized principally by a substantial decrease in the rate of rejections of the produce of the final texturizing anneal because of coating defects--such difficulties as bare spots, and metal-overlay pattern. Moreover, the magnetic properties may be improved because of improved control of the propagation of the internally oxidized zone of the steel.
