摘要: The present invention relates to a silicon powder, where the size of the silicon powder particles are between 3 and 30 μm, a particle size fraction D10 of the silicon powder particles is between 3 and 9 μm, and where the silicon powder particles have no, or substantially no, silicon particles with a size smaller than D10 attached to the surface. The silicon powder according to the present invention is produced by wet classifying produced silicon powders.
