Silicon metal (SI) bụ ihe ọla dị mkpa nwere ọtụtụ ngwa. Nke a bụ ụfọdụ isi ojiji nke silicon metal:
1. Semiconductor ihe: Silicon metal bụ otu n'ime ihe ndị kasị mkpa semiconductor ihe na ngwá electronic, nke a na-eji na-emepụta ihe dị iche iche electronic components, dị ka transistor, anyanwụ cell, fotovoltaic cell, photoelectric sensọ, wdg N'ime ngwá electronic, ndị na-emepụta ihe dị iche iche, dị ka transistors. ojiji nke ọla silicon dị nnọọ ukwuu.
2. Alloy Alloy: Enwere ike iji silicon ígwè na-emepụta ihe ndị na-emepụta ihe, nke nwere ike imeziwanye ike, ike na-eyi nguzogide nke alloy. A na-ejikarị silicon alloy metal eme ihe na ụlọ ọrụ nchara nchara na nkedo, dị ka igwe anaghị agba nchara, carbide cimented, alloy refractory na ndị ọzọ.
3. Silicate seramiiki ihe: silicon metal nwere ike iji kwadebe silicate seramiiki ihe, a seramiiki ihe onwunwe nwere magburu onwe mkpuchi ihe onwunwe na elu okpomọkụ na-eyi nguzogide, ọtụtụ ebe na-eji ọkụ eletrik, metallurgy, chemical ụlọ ọrụ, ceramics na ndị ọzọ ọrụ.
4. Silicone ogige: silicon metal nwere ike iji dị ka akụrụngwa nke silicone ogige maka mmepụta nke silicone roba, silicone resin, silicone mmanụ, silicone na ndị ọzọ ngwaahịa. Ngwaahịa ndị a nwere oke nguzogide okpomọkụ dị elu, nguzogide okpomọkụ dị ala, nguzogide corrosion kemịkalụ, nke a na-ejikarị na mbara igwe, ụgbọ ala, ihe owuwu, ahụike na mpaghara ndị ọzọ.
5. ubi ndị ọzọ: Silicon metal nwekwara ike iji maka nkwadebe nke silicon carbon fiber, silicon carbon nanotubes na ndị ọzọ dị elu-arụmọrụ ihe, maka nkwadebe nke thermal ikpuchi ihe, ihe n'elu mkpuchi, spark nozzles na na.
N'ozuzu, silicon metal bụ ezigbo ụlọ ọrụ akụrụngwa, nke a na-ejikarị na ngwá electronic, metallurgy, ceramics, chemical, medical and other fields. Site na mmepe sayensị na teknụzụ na-aga n'ihu, iji silicon ọla na-aga n'ihu na-agbasawanye ma na-emepe emepe, a ga-enwe atụmanya ahịa sara mbara.
2.Global mmepụta nke silicon ulo oru.
N'ihe banyere ike mmepụta: na 2021, zuru ụwa ọnụ mmepụta silicon mmepụta ike bụ 6.62 nde tọn, nke 4.99 nde tọn na-lekwasị na China (SMM2021 irè mmepụta ikike sample ọnụ ọgụgụ, ewezuga zombie mmepụta ikike nke banyere 5.2-5.3 nde tọn), ihe ruru 75%; Ike mmepụta nke mba ofesi bụ ihe dị ka nde tọn 1.33. N'ime afọ iri gara aga, ikike mmepụta nke mba ofesi kwụsiri ike n'ozuzu ya, na-echekwa ihe karịrị nde tọn 1.2-1.3..
China bụ ndị kasị emepụta silicon ụlọ ọrụ, Enterprise mmepụta na-eri uru, fotovoltaic / silicon / aluminom alloy na ndị ọzọ dị mkpa ọgwụgwụ n'ji ahịa na-lekwasị na China, na e nwere a siri ike na-eto eto, na-agbachitere isi ọnọdụ nke China si ulo oru silicon mmepụta ikike. A na-atụ anya na ahịa mmepụta silicon ụlọ ọrụ ụwa ga-abawanye ruo nde tọn 8.14 na 2025, China ka ga-achịkwa usoro uto ikike, yana ikike kacha elu ga-eru nde tọn 6.81, na-aza ihe fọrọ nke nta ka ọ bụrụ 80%. Na mba ofesi, ndị dike silicon ụlọ ọrụ ọdịnala na-eji nwayọọ nwayọọ na-agbasawanye ala, na-elekwasị anya na mba ndị ka na-emepe emepe dị ka Indonesia nwere ọnụ ahịa ike dị ala.
N'ihe banyere mmepụta: ngụkọta mmepụta nke silicon ụlọ ọrụ mmepụta ihe zuru ụwa ọnụ na 2021 bụ 4.08 nde tọn; China bụ ndị kasị ibu n'ụwa na-emepụta silicon ụlọ ọrụ, na mmepụta ruru 3.17 nde tọn (SMM data gụnyere 97, recycled silicon), na-aza 77%. Kemgbe 2011, China agafeela Brazil dị ka ndị na-emepụta ihe na ndị na-eji silicon ụlọ ọrụ.
Dabere na ọnụ ọgụgụ kọntinent, na 2020, Asia, Europe, South America na North America, oke nke mmepụta silicon ụlọ ọrụ bụ 76%, 11%, 7% na 5%, n'otu n'otu. Dị ka ọnụ ọgụgụ mba si kwuo, mmepụta silicon mmepụta ihe na mba ofesi na-elekwasị anya na Brazil, Norway, United States, France na ebe ndị ọzọ. Na 2021, USGS weputara data mmepụta silicon metal, gụnyere ferrosilicon alloy, na China, Russia, Australia, Brazil, Norway, na United States bụ ndị mbụ na-emepụta silicon metal.
