Description
Description
Ferrosilicon has many advantages in its manufacture and application, the most important of which is that it can be used to manufacture silicon wafers.
High purity silicon in ferrosilicon is an important raw material for manufacturing semiconductor devices. The manufacturing of silicon wafers requires the use of high purity silicon material. The silicon content of ferrosilicon is as high as 70%, which can provide enough silicon raw materials. In addition, the silicon in ferrosilicon has high purity, chemical inertness and thermal stability, which can guarantee the quality of silicon wafers.

Iron can be used as a doping agent of ferrosilicon. Silicon wafers usually need to be doped to change their electrical properties. Dopants can change the electrical properties of a silicon wafer by replacing impurity atoms with other atoms. And the iron in ferrosilicon can be used as dopant, doped into silicon wafer, change its electrical properties.
Ferrosilicon can also be used in heating furnaces where silicon wafers are made. The manufacture of silicon wafers requires a high temperature furnace, and ferrosilicon can be used to make such a furnace.
Ferrosilicon has thermal stability, can withstand high temperature environment, will not cause the furnace deformation or fracture. At the same time, ferrosilicon can also accelerate the heating and cooling in the furnace, and improve the production efficiency of silicon wafers.
