ORGANIC ACID ANION CONTAINING ALUMINUM SALT HYDROXIDE PARTICLES, PRODUCTION METHOD THEREOF, AND USE THEREOF

摘要

There are provided organic acid anion containingaluminum salt hydroxide particles represented by thefollowing general formula (I):M a [Al1-x M ' x] b A z B y (OH) n .cndot. mH2O (I)(wherein M is at least one cation selected from thegroup consisting of Na+, K+, NH4+ and H3O+, M' is at leastone metal cation selected from the group consisting ofCu2+, Zn2+, Ni2+, Sn4+, Zr4+, Fe2+, Fe3+ and Ti4+, A is atleast one organic acid anion, B is at least oneinorganic acid anion, and a, b, m, n, x, y and z satisfy0.7 = a = 1.35, 2.7 = b = 3.3, 0 = m= 5, 4 = n = 7,0 = x = 0.6, 1.7 = y = 2.4, and 0.001 = z= 0.5,respectively.)The particles are in the shape of grains, pairs,rectangular parallelepiped, disks (go stones),hexagonal plates, rice grains or cylinders and have auniform particle diameter.
