Silicon Metal o se oloa tau alamanuia taua tele e mafai ona faʻaaogaina i le uʻamea, uʻamea uʻamea, alumini (vaalele, vaalele & gaosiga vaega o taavale), ma masini optoelectronic silicon ma le tele o isi pisinisi. Ua ta'ua o le "masima" o pisinisi fa'aonaponei. O le silikoni uʻamea e faia mai le quartz ma le koko i totonu o le ogaumu faʻamafanafana eletise oloa faʻafefeteina. O le mea autu o le silicon content e tusa ma le 98%. O isi mea leaga o le uʻamea, alumini ma le calcium ma isi.
Silicon Metal lump na gaosia i le ogaumu faʻavevela eletise e ala ile quartz ma coke. Quartz o le a redox ma avea ma sua silikoni liusuavai. A maeʻa le malulu, o le a malo e pei ona tatou vaʻaia. O le fa'aputu u'amea silicon muamua e matua tele lava. Ona fai ai lea i ni fa'aputu laiti e ta'ua o le lapo'a masani. Silicon Metal lumps o le a 10-100mm.
