Kind Code:

A1

Abstract:

Particles of aluminum salt hydroxide containing an organic acid anion represented by the general formula (1): M_a[Al_1-xM’_x]_bA_zB_y(OH)_n·mH₂O (1) [wherein M represents at least one cation selected from the group consisting of Na⁺, K⁺, NH⁴⁺ and H₃O⁺, M’ represents at least one metal cation selected from the group consisting of Cu²⁺, Zn²⁺, Ni²⁺, Sn⁴⁺, Zr⁴⁺, Fe²⁺, Fe³⁺and Ti⁴⁺, A represents at least one organic acid anion, B represents 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]. The above particles have the form of a particle, one pair, a rectangular parallelepiped, a disk (a go stone), a hexagonal plate, a rice grain or a cylinder, and have a uniform particle diameter.
