摘要

PROBLEM TO BE SOLVED: To provide an Li-Al based lamellar double hydroxide composite particle powder large in plate face diameter, proper in thickness and having ultraviolet absorptivity, and also provide a method for production thereof.;SOLUTION: This Li-Al based lamellar double hydroxide composite particle powder comprises a Li-Al based lamellar double hydroxide particle and zirconium hydroxide, and is produced by mixing an anion-containing alkaline aqueous solution, a lithium salt aqueous solution and an aluminum compound capable of forming an aluminum ion, aging the resultant mixed solution to generate a core particle of the Li-Al based lamellar double hydroxide, adding the lithium salt aqueous solution and the above aluminum compound to the core particle- containing aqueous dispersion liquid, and then aging in the presence of a zirconium compound.;COPYRIGHT: (C)2003,JPO
