Procedure

Patent document 1 discloses a method of manufacturing a magnesium hydroxide particle having a large specific surface area by heating magnesium hydroxide and amorphous silicic acid in an aqueous medium to form magnesium silicate on the surface of a magnesium hydroxide particle. However, the reason that the specific surface area of the magnesium hydroxide particle obtained by this manufacturing method is large is assumed to be the influence of both magnesium silicate formed only on the surface and amorphous silicic acid which seems to remain unreacted partially. It is hard to say that the specific surface area of the magnesium hydroxide particle becomes large.
