High silicon ferrosilicon or siliceous alloys are used in the ferroalloy industry as reducing agents for the production of low carbon ferroalloys. Ferrosilicon added to cast iron can be used as inoculant of nodular cast iron, and can prevent the formation of carbide, promote the precipitation and spheroidization of graphite, and improve the performance of cast iron. In addition, ferrosilicon powder can be used as a suspended phase in the mineral processing industry, and as a coating for the electrode in the electrode manufacturing industry; High silicon ferrosilicon in the electrical industry can be used to prepare semiconductor pure silicon, in the chemical industry can be used to manufacture silicone and so on.
