Abstract
(EN)
Provided is an annealing separation agent capable of obtaining a grain-oriented electrical steel sheet having excellent appearance uniformity and adhesion of a forsterite coating. This annealing separation agent for a grain-oriented electrical steel sheet is formed by mixing 0.1-1.0 parts by mass of a phosphate per 100 parts by mass of the magnesia in terms of P with a magnesia containing 0.05-0.20 mass% of B and mainly composed of MgO, and adding titanium dioxide containing 0.050-1.0 mass% in total of one or two or more kinds of alkali metals and mainly composed of TiO2 in an amount of 1.0-10.0 parts by mass per 100 parts by mass of the magnesia, wherein the adsorption amount of P per 1 g of the titanium dioxide is 1.0×10-4 g or less.
