1.Compositions:Fe,Si,Al,Ca,Mn,Cr,P,S,C 2.Type:FeSi75-A,FeSi75-B,etc 3.To precipitate and diffuse deoxidation in steel making

      Applications in the production of other alloys include the manufacture of silicon steel for electro motors and cores, as well as coatings used during arc welding. One useful by-product of the production processes is silica fume, which is later added to concrete mixes to improve compressive and bonding strength .
