Introduction Of Ferrosilicon

Silicon (Taiwan, Hong Kong, said SI) is a chemical element, its chemical symbol is Si, formerly known as Silicon. Atomic number 14, relative atomic mass 28.09, have both amorphous and crystalline allotropes and allotropes are amorphous silicon and crystalline silicon.Belonging to the IVA class of metallic elements on the periodic table of the elements. Crystalline silicon steel gray, amorphous silicon is black, density 2.4g/cm3, 1420 c melting point, boiling point 2,355, belongs to the Atomic crystalline silicon crystals, hard and shiny, with semiconductor properties. Property comparison of silica and lively, at high temperatures can combine with oxygen and other elements, does not dissolve in water, nitric acid and hydrochloric acid, solution, hydrofluoric acid and lye, used in making alloys such as ferrosilicon, silicon steel, Silicon is an important semiconductor material, used in the manufacture of high-power transistors, Rectifier, solar cells, and so on.
