Abstract (en)
[origin: EP1698706A1] By using a treatment solution containing an Al compound in the form of a solution or a colloidal solution and a stable compound at a high temperature and having a viscosity of 25 mPa·s or less as an annealing separator, a superior annealing separation effect can be obtained without causing any dust problem and line contamination. In addition, when the above annealing separator is used in final annealing or the like in a manufacturing process of a grain-oriented electrical steel sheet, a grain-oriented electrical steel sheet can be obtained which has no forsterite coating or which has superior forsterite coating properties.
