Silicon simbi nhau

1. use.

  Silicon simbi (SI) chinhu chakakosha chesimbi chine huwandu hwakawanda hwekushandisa. Heano mamwe ekushandiswa kukuru kwesilicon simbi:

1. Semiconductor zvinhu: Silicon metal ndeimwe yezvinhu zvakakosha semiconductor zvinhu muindasitiri yemagetsi, iyo inoshandiswa kugadzira zvinhu zvakasiyana-siyana zvemagetsi, zvakadai se transistors, masero ezuva, photovoltaic masero, photoelectric sensors, nezvimwewo. kushandiswa kwesimbi nesilicon yakakura kwazvo.

2. Alloy zvinhu: metal silicon inogona kushandiswa kugadzira alloy zvinhu, izvo zvinogona kuvandudza simba, kuoma uye kupfeka kushorwa kwealloy. Metal silicon alloy inoshandiswa zvakanyanya musimbi yekunyungudutsa uye kukanda indasitiri, senge simbi isina tsvina, simende carbide, refractory alloy zvichingodaro.

3. Silicate ceramic zvinhu: metal silicon inogona kushandiswa kugadzirira silicate ceramic zvinhu, iyi ceramic zvinhu ine yakanakisa insulation zvivakwa uye yakakwirira tembiricha kupfeka kuramba, rinoshandiswa zvikuru musimba remagetsi, metallurgy, makemikari indasitiri, ceramics uye mamwe maindasitiri.

4. Mishonga yeSilicone: simbi yesilicon inogona kushandiswa semafuta emagetsi e-silicone ekugadzirwa kwesilicone rubber, silicone resin, silicone mafuta, silicone uye zvimwe zvigadzirwa. Izvi zvigadzirwa zvine yakanakisa kupisa tembiricha kuramba, kuderera kwekushisa kuramba, kemikari yekudzivirira kuturika, inoshandiswa zvakanyanya muaerospace, mota, kuvaka, zvekurapa nemamwe minda.

5. Mimwe minda: Silicon simbi inogonawo kushandiswa pakugadzira silicon carbon fiber, silicon carbon nanotubes uye mamwe ma-high-performance materials, nokuda kwekugadzirira kwezvinhu zvinopisa zvinopisa, zviputi zvepasi, spark nozzles nezvimwe zvakadaro.

Kazhinji, silicon simbi yakakosha kwazvo mumaindasitiri mbishi, inoshandiswa zvakanyanya mumagetsi, simbi, ceramics, makemikari, zvekurapa uye mamwe minda. Nekuenderera mberi kwekusimudzira kwesainzi uye tekinoroji, kushandiswa kwesimbi silicon kuri kuramba kuchiwedzera nekuvandudza, pachave nemusika wakakura tarisiro.

2.Global kugadzirwa kwemaindasitiri nesilicon.

Panyaya yehuwandu hwekugadzira: muna 2021, iyo yepasi rose maindasitiri silicon kugadzirwa kugona inosvika 6.62 miriyoni matani, ayo 4.99 miriyoni matani akaiswa muChina (SMM2021 inoshanda yekugadzira huwandu hwesample statistics, kusasanganisa zombie kugadzirwa kweanosvika 5.2-5.3 miriyoni matani), kuverenga kwe75%; Kumhiri kwemakungwa kugadzirwa kunogona kuita 1.33 miriyoni matani. Mumakore gumi adarika, mhiri kwemakungwa kugadzirwa kwesimba kwave kwakagadzikana sese, kunyanya kuchengetedza anopfuura mamirioni 1.2-1.3 matani..

China ndiyo yakakura inogadzira maindasitiri silicon, bhizinesi rekugadzira mutengo zvakanakira, photovoltaic/silicone/aluminium alloy uye mamwe akakosha ekupedzisira misika yevatengi akatarisana muChina, uye kune kwakasimba kudiwa kukura, kudzivirira chinzvimbo chikuru cheChina indasitiri yekugadzira silicon. Musika unotarisirwa kuti huwandu hwepasi rose hwekugadzira silicon huchakwira kusvika pamamiriyoni masere negumi nemana muna 2025, uye China icharamba ichitonga maitiro ekukura kwehuwandu, uye huwandu hwepamusoro huchasvika mamirioni mazana matanhatu nemakumi masere nerimwe ematani, achiverengera angangoita 80%. Mhiri kwemakungwa, echinyakare maindasitiri esilicon hofori ari kuwedzera zvishoma nezvishoma kudzika, achinyanya kutarisa nyika dzichiri kusimukira dzakaita seIndonesia dzine mutengo wakaderera wesimba.

Panyaya yekubuda: iyo yakazara yakabuda yepasi rose maindasitiri silicon muna 2021 ndeye 4.08 miriyoni matani; China ndiyo inogadzira pasi rose inogadzira silicon yemaindasitiri, ine kubuda kunosvika 3.17 miriyoni matani (SMM data inosanganisira 97, yakadzokororwa nesilicon), inoverengera makumi manomwe nenomwe muzana. Kubva 2011, China yakapfuura Brazil semugadziri mukuru pasi rose uye mutengi wemaindasitiri silicon.

Zvinoenderana nenhamba dzekondinendi, muna 2020, Asia, Europe, South America neNorth America, chikamu chekugadzirwa kwemaindasitiri silicon i76%, 11%, 7% uye 5%, zvichiteerana. Zvinoenderana nenhamba dzenyika, kugadzirwa kwesilicon kwemhiri kwemakungwa kunonyanya kutariswa muBrazil, Norway, United States, France nedzimwe nzvimbo. Muna 2021, iyo USGS yakaburitsa silicon simbi yekugadzira data, kusanganisira ferrosilicon alloy, uye China, Russia, Australia, Brazil, Norway, uye United States dzakatora pekutanga mukugadzirwa kwesimbi yesilicon.
