Polycrystalline silicon is mainly used to produce monocrystalline silicon and satellite solar energy cells.
Monocrystalline silicon (silicon semiconductor) is a derivative of polycrystalline silicon and an excellent material in the production of integrated circuits and electronic components.
1. Present status of production
The semiconductor material industry in China is weak. The total output only accounts for 1 - 2% of the world total. Both the capacity and the output of polycrystalline silicon had a drop during the Seventh Five-year Plan period. Table 1 shows the detail. The production of monocrystalline silicon remained basically the same. ...
