When used as a filler in a resin with excellent moisture resistance, it is coated with a double oxide as a spherical coated magnesium oxide powder with excellent filling properties and fluidity, and the average shape factor is 1.25 or less. A spherical coated magnesium oxide powder is provided. In addition, the presence of a compound of an element that forms a double oxide on the surface of the magnesium oxide powder, followed by melting at a high temperature, the magnesium powder surface is coated with the double oxide and spheroidized. A method for producing magnesium powder is provided. Furthermore, a resin composition containing the spherical coated magnesium oxide powder and an electronic device using the resin composition are provided. |
