Abstract

See full text

A magnesium oxide powder having excellent dispersibility and a small average particle diameter as well as a uniform particle diameter and containing no very small size particles is obtained. A magnesium oxide powder which is particles, wherein the magnesium oxide powder has a BET specific surface area of 5 m2/g or more, a cumulative 50% particle diameter (D50) obtained in the measurement of laser diffraction scattering particle size distribution of 0.3 to 1.5 μm, a ratio of a cumulative 90% particle diameter (D90) to a cumulative 10% particle diameter (D10) (D90/D10) obtained in the measurement of laser diffraction scattering particle size distribution of 5 or less, and a D10 of 0.1 μm or more.
