Products Description
The preparation method of Silicon Metal powder is relatively simple and easy, and the preparation principle is also very simple and easy to understand, that is, after a certain crude silicon powder is dispersed, the inert gas is sent into the plasma arc, and the instant heating makes the coarse silicon powder evaporate into silicon steam at a relatively high temperature, and the silicon steam then enters the cooling zone, is condensed down, and becomes a nanoscale metal silicon powder.
Chemical vapor deposition method: silane is decomposed into silicon and hydrogen under the condition of high hydrogen dilution under the action of heat, microwave, laser, plasma and other external energy, which is quickly condensed in the gas phase environment, so as to prepare nano silicon powder;
Ball milling method: The use of mechanical rotation and the interaction between particles to produce large friction to grind the size of the silicon material into a nanometer size powder. The metal silicon powder produced by ball milling method has high impurity content, the particle size distribution can not be well controlled, and the post-treatment is complicated.
