PROBLEM TO BE SOLVED: To provide a dispersant for inorganic powder, by which inorganic powder can be dispersed stably in a dispersion medium over a long time without precipitating inorganic powder or even precipitated inorganic powder can easily be dispersed again and to provide a dispersant composition for inorganic powder, which contains the dispersant for inorganic powder. SOLUTION: The dispersant for inorganic powder contains at least one selected from the compounds shown by formula (I): RO-(AO)<SB>a</SB>(EO)<SB>b</SB>-SO<SB>3</SB>M (wherein R is a 1-22C alkyl or alkenyl group; AO is a 3-18C oxyalkylene group; EO is an oxyethylene group; (a) is a number of 1-20 showing the average molar number of added EO; b is a number of 1-100; M is a cation). The dispersant composition for inorganic powder contains this dispersant. COPYRIGHT: (C)2007,JPO&INPIT
