METHOD FOR MANUFACTURING FLAKE-SHAPED HYDROTALCITE-TYPE PARTICLE

摘要

Provided is a manufacturing method with which it is possible to easily and conveniently provide flake-shaped hydrotalcite-type particles having superior glide, without the introduction of special devices or equipment. This method for manufacturing flake-shaped hydrotalcite-type particles includes: a step (I) in which a precursor is obtained using an aluminum compound and at least one compound selected from the group consisting of zinc compounds and compounds containing an element from group 2 of the periodic table as raw materials; and a step (II) in which the precursor is kept in an atmosphere with a temperature of 75-150°C and a relative humidity of 75-100%. The half-width of peaks originating from a (003) plane of the precursor is 0.4 or greater.
