PROBLEM TO BE SOLVED: To provide a method for producing an inorganic composite powder suppressed in luster and to provide an inorganic composite powder.SOLUTION: There are provided: [1] a method for producing an inorganic composite powder by growing silica on an inorganic powder which comprises the following steps 1 and 2 and [2] an inorganic composite powder obtained by the production method. Step 1: a step of mixing a cationic surfactant, one or more inorganic powders selected from the group consisting of talc, mica and barium sulfate, a hydrophilic organic solvent and water to produce an aqueous dispersion of the inorganic powder and Step 2: a step of adding a silica source to the aqueous dispersion obtained in the step 1 to grow silica under the conditions that the mass ratio of the silica source (in terms of SiO2)/the inorganic powder is 0.1 or more and 10 or less.COPYRIGHT: (C)2015,JPO&INPIT【課題】光沢が抑制された無機複合粉体の製造方法、及び無機複合粉体を提供する。【解決手段】[1]下記工程1及び2を有する、無機粉体上にシリカを成長させた、無機複合粉体の製造方法、[2]当該製造方法により得られる、無機複合粉体。工程1:カチオン界面活性剤と、タルク、マイカ、及び硫酸バリウムからなる群から選ばれる1種以上の無機粉体と親水性有機溶媒と水とを混合して、無機粉体の水分散液を製造する工程工程2:前記工程1で得られた水分散液に、シリカ源を添加して、シリカ源(SiO2換算)/無機粉体の質量比が0.1以上10以下の条件でシリカを成長させる工程【選択図】図1
