Litaba tsa tšepe tsa silicon

  1. tshebediso.

  Silicon metal (SI) ke thepa ea bohlokoa ea tšepe e nang le mefuta e mengata ea lisebelisoa. Mona ke tse ling tsa ts'ebeliso ea mantlha ea tšepe ea silicon:

1. Lisebelisoa tsa semiconductor: Silicon metal ke e 'ngoe ea lisebelisoa tsa bohlokoa ka ho fetisisa tsa semiconductor indastering ea elektronike, e sebelisetsoang ho etsa likarolo tse sa tšoaneng tsa elektronike, tse kang li-transistors, lisele tsa letsatsi, lisele tsa photovoltaic, li-sensor tsa photoelectric, joalo-joalo. tšebeliso ea silicon ea tšepe e kholo haholo.

2. Lisebelisoa tsa alloy: silicon ea tšepe e ka sebelisoa ho etsa lisebelisoa tsa alloy, tse ka ntlafatsang matla, ho thatafala le ho apara ho hanyetsa ha motsoako. Metal silicon alloy e sebelisoa haholo indastering ea ho qhibilihisa le ho lahla, joalo ka tšepe e sa hloekang, carbide e entsoeng ka samente, alloy refractory joalo-joalo.

3. Lisebelisoa tsa li-ceramic tsa silicate: silicon ea tšepe e ka sebelisoa ho lokisetsa lisebelisoa tsa silicate ceramic, thepa ena ea ceramic e na le thepa e babatsehang ea ho pata le ho hanyetsa mocheso o phahameng oa mocheso, o sebelisoang haholo ka matla a motlakase, metallurgy, indasteri ea lik'hemik'hale, li-ceramics le liindasteri tse ling.

4. Li-silicone metsoako: tšepe ea silicon e ka sebelisoa e le lisebelisoa tse tala tsa metsoako ea silicone bakeng sa tlhahiso ea rabara ea silicone, resin ea silicone, oli ea silicone, silicone le lihlahisoa tse ling. Lihlahisoa tsena li na le khanyetso e ntle ea mocheso o phahameng, khanyetso ea mocheso o tlase, khanyetso ea kutu ea lik'hemik'hale, e sebelisoang haholo sebakeng sa sefofane, likoloi, kaho, bongaka le masimo a mang.

5. Likarolo tse ling: tšepe ea silicon e ka boela ea sebelisoa bakeng sa ho lokisa silicon carbon fiber, silicon carbon nanotubes le lisebelisoa tse ling tse sebetsang hantle, bakeng sa ho lokisa lisebelisoa tsa ho futhumatsa mocheso, ho roala holim'a thepa, li-nozzles tsa spark joalo-joalo.

Ka kakaretso, tšepe ea silicon ke thepa e tala ea bohlokoa haholo ea indasteri, e sebelisoang haholo ho elektronike, metallurgy, ceramics, lik'hemik'hale, bongaka le masimo a mang. Ka tsoelo-pele e tsoelang pele ea saense le thekenoloji, tšebeliso ea silicon ea tšepe e boetse e tsoela pele ho atolosa le ho ntlafatsa, ho tla ba le menyetla e pharaletseng ea 'maraka.

2.Tlhahiso ea lefats'e ea silicon ea indasteri.

Mabapi le matla a tlhahiso: ka 2021, matla a tlhahiso ea silicon lefatšeng ka bophara ke lithane tse limilione tse 6.62, tseo ho tsona lithane tse limilione tse 4.99 li tsepamisitsoeng Chaena (SMM2021 lipalo-palo tse sebetsang hantle tsa tlhahiso ea tlhahiso, ntle le tlhahiso ea zombie ea lithane tse ka bang limilione tse 5.2-5.3), e etsang 75%; Bokhoni ba tlhahiso ea mose ho maoatle bo ka ba lithane tse limilione tse 1.33. Lilemong tse leshome tse fetileng, matla a tlhahiso ea mose ho maoatle a tsitsitse ka kakaretso, ha e le hantle a boloka lithane tse fetang limilione tse 1.2-1.3..

China ke mohlahisi e moholo ka ho fetisisa oa silicon ea indasteri, melemo ea litšenyehelo tsa tlhahiso ea khoebo, photovoltaic / silicone / aluminium alloy le limmaraka tse ling tsa bohlokoa tsa bareki li tsepamisitsoe Chaena, 'me ho na le kholo e matla ea tlhokahalo, e sireletsang boemo bo ka sehloohong ba matla a tlhahiso ea silicon ea indasteri ea Chaena. Mmaraka o lebelletsoe hore matla a tlhahiso ea liindasteri tsa lefats'e a tla nyolohela ho lithane tse limilione tse 8.14 ka 2025, mme China e ntse e tla laola mokhoa oa kholo ea bokhoni, 'me matla a holimo a tla fihla ho lithane tse limilione tse 6.81, tse etsang karolo ea 80%. Ka mose ho maoatle, linatla tsa khale tsa liindasteri tsa silicon li ntse li hola butle butle, li shebane haholo le linaha tse tsoelang pele joalo ka Indonesia tse nang le litšenyehelo tse tlase tsa matla.

Mabapi le tlhahiso: kakaretso ea silicon ea indasteri ea lefats'e ka 2021 ke lithane tse limilione tse 4.08; China ke mohlahisi e moholo ka ho fetisisa lefatšeng oa silicon ea indasteri, e nang le tlhahiso e fihlang ho lithane tse limilione tse 3.17 (data ea SMM e kenyelletsang 97, silicon e nchafalitsoeng), e etsang 77%. Ho tloha ka 2011, China e fetile Brazil joalo ka mohlahisi e moholo ka ho fetisisa lefatšeng le moreki oa silicon ea indasteri.

Ho ea ka lipalo-palo tsa k'honthinente, ka 2020, Asia, Europe, Amerika Boroa le Amerika Leboea, karolo ea tlhahiso ea silicon ea indasteri ke 76%, 11%, 7% le 5%, ka ho latellana. Ho ea ka lipalo-palo tsa naha, tlhahiso ea silicon ea mose ho maoatle e tsepamisitsoe haholo Brazil, Norway, United States, Fora le libakeng tse ling. Ka 2021, USGS e ile ea lokolla lintlha tsa tlhahiso ea tšepe ea silicon, ho kenyelletsa le motsoako oa ferrosilicon, 'me Chaena, Russia, Australia, Brazil, Norway le United States li ile tsa nka sebaka sa pele tlhahisong ea tšepe ea silicon.
