ABSTRACT:
A jet pulverizing method is described for preparing silicon seed particles from silicon feed particles without contamination. The method comprises accelerating silicon feed particles by fluid jet energy and colliding them with each other within a pulverizing chamber to fracture or split them into small particles which are recovered for use as seed particles. The method is characterized by the technique that silicon particles fluidized within the pulverizing chamber are formed into a dilute-phase fluidized bed with low particle density. Thus, the generation of fine powders may be suppressed and additional sieving to separate larger particles is not required.
