<p>There are provided organic acid anion containing aluminum salt hydroxide particles represented by the following general formula (I):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒM a [Al 1-x M' x ] b A z B y (OH) n ·mH 2 O€ƒ€ƒ€ƒ€ƒ€ƒ(I)
(wherein M is at least one cation selected from the group consisting of Na + , K + , NH 4+ and H 3 O + , M' is at least one metal cation selected from the group consisting of Cu 2+ , Zn 2+ , Ni 2+ , Sn 4+ , Zr 4+ , Fe 2+ , Fe 3+ and Ti 4+ , A is at least one organic acid anion, B is at least one inorganic acid anion, and a, b, m, n, x, y and z satisfy 0.7 ‰¤ 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 a uniform particle diameter.</p> |
