Silicon Metal shine samfurin masana'antu mai mahimmanci wanda za'a iya amfani dashi a cikin ƙarfe, simintin ƙarfe, aluminum (jirgin sama, jirgin sama & samar da sassan mota), da na'urar siliki optoelectronic da sauran masana'antu da yawa. An san shi da "gishiri" na masana'antu na zamani. An yi siliki na ƙarfe daga ma'adini da coke a cikin tanderun dumama kayan da ke narkewa. Babban abun ciki na silicon shine kusan 98%. Sauran najasa sune baƙin ƙarfe, aluminum da calcium da sauransu.
An samar da dunƙulen Silicon Metal a cikin tanderun dumama lantarki ta quartz da coke. Quartz zai zama redox kuma ya zama narkakken ruwa na silicon. Bayan sanyaya, zai kasance da ƙarfi kamar yadda muke gani. Kullin karfen siliki na farko yana da girma sosai. Sa'an nan za a sanya shi zuwa ƙananan ƙullun da muke kira daidaitaccen girman. Silicon Metal Lumps zai zama 10-100mm.
