Alunite type compound particles represented by the following general formula (I) and having a specific value of D75 /D25 when D25 is the particle diameter of particles which account for 25 % of the total and D 75 is the particle diameter of particles which account for 75 % of the total in the cumulative particle size distribution curve measured by a laser diffraction method: Ma[Al 1-x M'x]3 (SO4<2-> )y(OH)z mH2O (I) wherein M is at least one cation selected from the group consisting of Na<+> , K+ , NH4<+> and H3O<+> , M' is at least one cation selected from the group consisting of Cu<2+> , Zn<2+> , Ni<2+> , Sn<4+> , Zr<4+> and Ti<4+> , and a, m, x, y and z satisfy 0.8 | a | 1.35, 0 | m | 5, 0 | x | 0.4, 1.7 | y | 2.5, and 4 | z | 7, respectively. The above particles of the present invention have a small average particle diameter, are spherical, disk-like or hexagonal and have an extremely narrow particle size distribution.
