Spherical magnesium hydroxide particles having a high specific surface area, and magnesium oxide particles spherical, as well as methods for their preparation

摘要

PROBLEM TO BE SOLVED: To provide spherical magnesium hydroxide particles and magnesium oxide particles having a large specific surface area, and a method for producing the same.;SOLUTION: 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 grain size distribution measurement, of 1.0 to 5.0 μm; and a specific surface area of 10 m²/g or higher.;COPYRIGHT: (C)2013,JPO&INPIT
