Polysilicon is composed of a great number of silicon atoms and many small crystal grains. It is produced by metal silicon (namely industrial silicon)through chemical reaction, purification, and reduction to grain the high-purity materials (namely reduction silicon).
Appearance:General dark grey,opaque,with metal luster.
Properties:Its density is between 2.32 and 2.34 with melting point of 1410 ¡æ, boiling point of 2355 ¡æ, dissolving in the hydrofluoric acid and nitric acid mixture while not in water, nitrate and hydrochloric acid.
Usage:It is mainly used for semiconductors and solar cells and can be drawn silicon materials. In the electronics industry it is widely used in the manufacture of semiconductor radios, tape recorders, refrigerators, color televisions, video recorders, computers and other basic materials.
