The invention relates to a dispersion method for nanometer power materials. The method which is directed to a case that nanometer power materials are easy to agglomerate is characterized in that: a dispersant and a mechanical dispersion method are adopted; the nanometer power materials are firstly classified; and a matched dispersant and a matrix material are selected, placed in a dispenser, and dispersed under high speed rotation with a speed of 1000 to 10000 r/min. A single powder material is subjected to washing, extraction filtering and drying, a material of the powder material, the matrix and the dispersant are extruded, cut into granules, and dried, and the dispersed material is subjected to washing with waterless ethanol, extraction filtering and vacuum drying to prepare the dispersible nanometer power material. The dispersed nanometer power material can be matched with a plurality of chemical substances to prepare a plurality of products with high added value, so the dispersion method is suitable for
