Ferrosilicon - an overview ScienceDirect Topics

Ferrosilicon is a basis for manufacture of pre-alloys like magnesium ferrosilicon (MgFeSi), used for production of ductile iron. MgFeSi contains 3%–42% magnesium and small amounts of rare-earth metals. Ferrosilicon is also important as an additive to cast irons for controlling the initial content of silicon.

Polysilicon Production - an overview ScienceDirect Topics

Renewable Energy Corporation, an integrated producer of silicon, wafers, cells and modules, projects that polysilicon production capacity will increase from under 50,000 MT in 2008 to 125–1,60,000 MT in 2012. This would exceed their projection of demand for polysilicon in 2012, potentially leading to a price drop.
