PROBLEM TO BE SOLVED: To provide a method for easily producing magnesium oxide particles whose primary particles are spherical. SOLUTION: A magnesium hydroxide composition containing 3-20 parts by mol (expressed in terms of acetic acid group) of an acetate based on 100 parts by mol of magnesium hydroxide is prepared and fired at 1,000-1,800°C. The acetate is at least one selected from alkali metal acetates, alkaline earth metal acetates and ammonium acetate. COPYRIGHT: (C)2009,JPO&INPIT
