Silanemusanganiswa wesilicon nehydrogen, uye izwi rinowanzoreva nhevedzano yemakomboni. Silane inonyanya kusanganisira monosilane (SiH4), disilane (Si2H6) uye mamwe epamusoro-level silicon hydrogen komisheni, ine general formula SinH2n +2. Nekudaro, mukugadzirwa chaiko, isu tinowanzo taura nezve monosilane (kemikari formula SiH4) se "silane".

Electronic-giredhisilane gasiinonyanya kuwanikwa nemhando dzakasiyana-siyana dzekuita distillation uye kucheneswa kwesilicon powder, hydrogen, silicon tetrachloride, catalyst, etc. Silane ine kuchena kwe3N kusvika ku4N inonzi industrial-grade silane, uye silane ine kuchena kweinopfuura 6N inonzi electronic-grade silane gas.

Senzvimbo yegesi yekutakura zvinhu zvesilicon,silane gasirave rinokosha rinokosha gasi risingagoni kutsiviwa nemamwe akawanda manyuko esilicon nekuda kwekuchena kwayo kwepamusoro uye kugona kuwana kutonga kwakanaka. Monosilane inogadzira crystalline silicon kuburikidza nepyrolysis reaction, inova imwe yenzira dzekugadzira hukuru hwegranular monocrystalline silicon uye polycrystalline silicon munyika.

Silane maitiro

Silane (SiH4)igasi risina ruvara rinosangana nemhepo uye rinokonzera kudzipwa. Rinofanana nesilicon hydride. Iyo kemikari formula yeSilane ndeyeSiH4, uye zvirimo zvakakwirira se99.99%. Patembiricha yemumba uye kumanikidzwa, silane igasi rine muchetura rinonhuwa. Nzvimbo yekunyungudika ye silane i -185 ℃ uye nzvimbo yekuvira i -112 ℃. Pane tembiricha yemumba, silane yakagadzikana, asi kana ichipisa kusvika 400 ℃, inoora zvachose kuita gaseous silicon nehydrogen. Silane inopfuta uye inoputika, uye inopisa zvakanyanya mumhepo kana halogen gasi.

Nzvimbo dzekushandisa

Silane ine huwandu hwakawanda hwekushandisa. Pamusoro pekuve iyo inonyanya kushanda nzira yekubatanidza masilicon mamorekuru kumusoro kwesero panguva yekugadzirwa kwemasero ezuva, inoshandiswa zvakanyanya mukugadzira zvidyarwa zvakaita semiconductors, flat panel displays, uye girazi rakavharwa.

Silanendiyo silicon sosi yemakemikari vapor deposition maitiro akadai sekristaro imwe chete silicon, polycrystalline silicon epitaxial wafers, silicon dioxide, silicon nitride, uye phosphosilicate girazi muindasitiri yesemiconductor, uye inoshandiswa zvakanyanya mukugadzira nekuvandudza masero ezuva, silicon copier zvigubhu, mafotoelectric sensors, yakakosha girazi fibers.

Mumakore achangopfuura, kushandiswa kwepamusoro-tekinoroji yemasilaini kuchiri kubuda, kusanganisira kugadzirwa kwedhakamics, zvinhu zvinoumbwa, zvinoshanda, biomaterials, zvinhu zvine simba guru, nezvimwewo, zvichiva hwaro hwehunyanzvi hutsva hwakawanda, zvishandiso zvitsva, uye zvishandiso zvitsva.
