Silicon Metal nigicuruzwa cyingenzi cyinganda zirashobora gukoreshwa mugukora ibyuma, ibyuma, aluminium (indege, indege & ibinyabiziga bikora), hamwe nibikoresho bya silicon optoelectronic nizindi nganda nyinshi. Bizwi nka "umunyu" winganda zigezweho. Silicon yicyuma ikozwe muri quartz na kokiya mu bicuruzwa byo gushyushya amashanyarazi. Ibyingenzi byingenzi bigize silicon ni hafi 98%. Ibisigaye byanduye ni fer, aluminium na calcium nibindi.
Silicon Metal lump yakozwe mu ziko ryashyushya amashanyarazi na quartz na kokiya. Quartz izaba redox hanyuma ihindurwe amazi ya silicon. Nyuma yo gukonja, bizaba bikomeye nkuko tubibona. Icyuma cya silicon cyibanze ni kinini cyane. Noneho bizakorwa mubice bito twita ubunini busanzwe. Silicon Metal Lumps izaba 10-100mm.
