SPHERICAL MAGNESIUM HYDROXIDE PARTICLES AND MAGNESIUM OXIDE PARTICLES HAVING A LARGE SPECIFIC SURFACE AREA, AS WELL AS METHOD FOR PRODUCING SAME

摘要

Provided are spherical magnesium hydroxide particles and magnesium oxide particles having a large specific surface area, as well as a method for producing the same. The magnesium hydroxide particles and magnesium oxide particles are spherical particles that are obtained when scale-like primary particles aggregate. The particles have a volume-cumulative 50% grain diameter (D50) as determined by laser diffraction scattering-type sizing that is between 1.0 and 5.0 µm and a specific surface area of 10 m2/g or higher.
