Abstract

A method for conveying silicon fragments has the silicon fragments being conveyed over a conveyor surface, which is made from hyperpure silicon. There is a vibrating conveyor, and during the conveying, the sharp edges of the silicon fragments are rounded and mechanical-physical decontamination takes place. The vibrating conveyor has a conveyor surface which is made from hyperpure silicon. A second vibrating conveyor unit has a conveyor surface which is made from hyperpure silicon and has passage openings therethrough.
