I-Silicon Metal iwumkhiqizo wezimboni obaluleke kakhulu ongasetshenziswa ekwenzeni insimbi, insimbi yokusansimbi, i-aluminium (indiza, izindiza kanye nokukhiqizwa kwezingxenye zezimoto), kanye nedivaysi ye-silicon optoelectronic nezinye izimboni eziningi. Kwaziwa ngokuthi "usawoti" wezimboni zesimanje. I-silicon yensimbi yenziwe nge-quartz ne-coke emikhiqizweni yokuncibilikisa isithando somlilo sikagesi. Isithako esiyinhloko sokuqukethwe kwe-silicon cishe singama-98%. Okunye ukungcola yi-iron, i-aluminium ne-calcium njll.
I-Silicon Metal lump yakhiqizwa esithandweni sokushisa sikagesi nge-quartz ne-coke. I-quartz izoba yi-redox futhi ibe uketshezi lwe-silicon oluncibilikisiwe. Ngemva kokupholisa, izoqina njengoba sibona. I-primal silicon metal lump inkulu kakhulu. Ngemva kwalokho izokwenziwa ibe izigaxa ezincane esizibiza ngosayizi ojwayelekile. I-Silicon Metal Lumps izoba ngu-10-100mm.
