Silicon Briquette is made of leftover bits and pieces of FeSi and Silicon Metal,it cost low because of recycling material,by reprocess of crushing,proportioning,mixing,chemical analysis,pressing,the silicon content can reach to 70%,60%,50% etc,rest of elements are Ca,C,Fe,Al and trace elements,Cr,Mn,P,S.Nowadays many steel plants use silicon ball instead of ferrosilicon,which saves a lot of raw material cost, create huge profits.
