Improved Jet-Mill Silicon GrinderProposed refinement in jet-mill grinding of silicon reduces proportion of unusable, overly ground particles. Particles serve as seeds for growth of silicon from vapor. In new grinding apparatus, particle separator distinct from collision chamber. Particle collides only once before sorted for size. If proper size, extracted; if not, returned to chamber for another collision.
