Procedure

Aluminum hydroxide as a starting raw material was first ground in a ball mill, etc. and adjusted to a particle size of 1.0 μm. This product was mixed with water to produce a 50% by weight slurry containing the raw material particles in an amount of 50% by weight based on the weight of the slurry. Sodium phosphate was added to this slurry to give as phosphoric acid ions in an amount of 5.0×10−3 mol per mol of aluminum hydroxide, and was thoroughly mixed and dissolved.
