PROBLEM TO BE SOLVED: To provide flaky mica powder excellent in oil absorption properties and further combining satisfactory glossy feeling and use feeling.SOLUTION: Provided is flaky mica powder containing flaky mica grains in which edge parts are curled, and in which the median particle diameter of the whole powder is 5 to 30 μm, the average thickness is 0.05 to 0.35 μm, and also, bulk density is 0.05 to 0.10 g/mL.Preferably, its oil absorption is 80 to 120 mL/100 g. Also provided is a method for producing flaky mica in which edge parts are curled obtainable by subjecting the above powder to coarse pulverizing and wet pulverizing, thereafter subjecting the same to classification selection to the median particle diameter of 5 to 30 μm and the average thickness of 0.05 to 0.35 μm by a centrifugal separator or the like and subjecting the fine powder after the classification to a high speed collision type pulverizer such as a jet pulverization mill as well.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】吸油性に優れるとともに、良好な光沢感および使用感を兼ね備えた薄片状雲母粉末の提供。【解決手段】端部がカールした薄片状雲母粒子を含み、粉末全体のメジアン粒子径が5~30μm、平均厚みが0.05~0.35μmであり、かつ嵩比重が0.05~0.10g/mLである薄片状雲母粉末。好ましくは吸油量が80~120mL/100gである薄片状雲母粉末。前記粉末は、粗粉砕、湿式粉砕の後、メジアン粒子径5~30μm、平均厚み0.05~0.35μmに遠心分離機等により分級選別し、分級後の微粉末をさらにジェット粉砕ミル等の高速衝突型粉砕機に供することによって得られる端部がカールした薄片状雲母の製造方法。【選択図】図2
