Ferrosilicon alloy is composed of iron and silicon. Uses of silicon: covalent bond having Si-O bond is an ionic bond characteristics of 50% (covalent bond directional supply of rare earth ferrosilicon alloy, ionically non-directional). Due to the unique structure of organic silicon, both the performance of inorganic materials and organic materials with low surface tension, viscosity-temperature coefficient, high compression, the basic nature of higher gas permeability, and has high temperature resistance, electrical insulation, resistance to oxidation stability resistance, weather resistance, flame retardant, water-repellent, corrosion-resistant, non-toxic, odorless and physiologically inert and other outstanding features. Ferrosilicon alloy is composed of iron and silicon. Ferrosilicon smelting raw materials: silica. Impurities in the silica content is relatively low. Silica impurities mainly refers Al2O3, MgO, CaO, P2O5 and other high quality rare earth ferrosilicon alloy, these impurities into the slag materials are rare earth ferrosilicon alloy, is not conducive to the production of ferrosilicon antegrade. Therefore, to ensure the quality and smooth production of silica, Al2O3 content must be less than 0.5%, MgO and CaO content is less than 1% of the sum.
