Beschreibung
Zusammenfassung:The invention relates to spherical, nonporous silicon particles having average particle sizes (d50) of 1 to 10 pm and a silicon content of 97 to 99.8 wt%, the silicon content relating to the total weight of the silicon particles minus any oxygen content. 本发明涉及具有1至10pm的平均粒径(d)以及97至99.8wt％的硅含量的球形无孔硅颗粒，硅含量与硅颗粒的总重量减去任何氧含量有关。
