Ma ka ʻoihana, hana pinepine ʻia ke silika metala ma ka hoʻemi ʻana i ke silica me ke kalapona i loko o ka umu uila.
Ka hoʻohālikelike hoʻohālikelike kemika: SiO2 + 2C→Si + 2CO
ʻO ka maʻemaʻe o ke silika i loaʻa i kēia ala ʻo 97 ~ 98%, i kapa ʻia ʻo ka silika metala.A laila hoʻoheheʻe ʻia a hoʻihoʻi hou ʻia, a hoʻoneʻe ʻia nā mea haumia me ka waikawa e loaʻa ai ka silika metala me ka maʻemaʻe o 99.7 ~ 99.8%.
ʻO ka hoʻohui ʻana o ke kilika metala he silika ka nui, no laila he mau waiwai like me ke silika.
He ʻelua alotrope ka Silicon:silikona amorphous a me ke silika crystalline.
ʻO ke kilika amorphous he aʻeleʻele hina hinahe microcrystal maoli ia.
Loaʻa iā Crystalline silicone kahale anianiawaiwai semiconductor o daimana, kaHe 1410°C ka helu hehee, ʻo 2355°C ka helu hoʻolapalapa, ʻo 7 ka paʻakikī o ka Moh, a he maʻalili.Amorphous silikona mea kemika a hikipuhi ikaika i ka oxygen.Hoʻopili ʻo ia me nā metala ʻole e like me ka halogen, nitrogen a me ke kalapona i ka wela kiʻekiʻe, a hiki ke launa pū me nā metala e like me ka magnesium, calcium a me ka hao e hana i nā silicides.ʻAneʻane hiki ʻole ke hoʻoheheʻe ʻia ke silikona Amorphous i loko o nā ʻakika inorganic a me nā mea hoʻokalakupua me ka waika hydrofluoric, akā hiki ke hoʻoheheʻe ʻia i nā ʻakika hui ʻia o ka waikawa nitric a me ka waika hydrofluoric.Hiki ke ho'ohehe'e i ke silika amorphous a ho'oku'u i ka hydrogen.ʻAʻole hiki ke hoʻohana ʻia ʻo Crystalline silicon, ʻaʻole ia e hui pū me ka oxygen a hiki i ka wela kiʻekiʻe, ʻaʻole hiki ke hoʻoheheʻe ʻia i loko o nā waika inorganic a me ka waikawa organik, akā hiki ke hoʻoheheʻe ʻia i nā ʻakika hui ʻia o ka waikawa nitric a me ka waika hydrofluoric a me ka hopena sodium hydroxide.
Hoʻohana ʻia ka nui o ka silika no ka hoʻoheheʻe ʻana i ka ferrosilicon alloy ma ke ʻano he mea hoʻohui i ka ʻoihana hao a me ke kila, a ma ke ʻano he mea hoʻohaʻahaʻa i ka hoʻoheheʻe ʻana i nā ʻano metala.He mea maikaʻi hoʻi ʻo Silicon i nā alumini alumini, a ʻo ka hapa nui o nā alumini alumini i loko o ke silika
