Silicon is produced in the form of pieces ranging in size from 20 to 300 mm with an acceptable fraction content of less than 20 mm no more than 10% of the batch weight.
The surface of silicon pieces should not contain inclusions of slag, sand and other foreign materials, visible to the naked eye. Darkening of the silicon surface during self-breaking of hot ingots, as well as the presence of tarnished colors are not considered unacceptable.
On the surface of pieces of silicon intended for the production of aluminum-silicon alloys of various grades, traces of non-stick filling, segregation deposits, silicon splashes, tarnish films and individual minor slag inclusions.
