3303,441,553 chowonjezera chachitsulo cha silicon cha aluminium alloy kuponyera Chithunzi chowonetsedwa

3303,441,553 silicon zitsulo zowonjezera zopangira aluminium alloy kuponyera

Kachitidwe:

Chitsulo cha silicon chikhoza kugawidwa molingana ndi zomwe zili muzitsulo zitatu zazikulu zachitsulo, aluminiyamu ndi calcium zomwe zili mmenemo, zomwe zingathe kugawidwa mu553, 441, 411, 421, 3303,etc. zosiyanasiyana.
M'mafakitale, zitsulo zachitsulo silicon nthawi zambiri zimapangidwa ndi kuchepetsa silika ndi carbon mung'anjo yamagetsi.
Chemical reaction equation: SiO2 + 2C → Si + 2CO

M'mafakitale, silicon yachitsulo nthawi zambiri imapangidwa pochepetsa silika ndi kaboni mung'anjo yamagetsi.

Chemical reaction equation: SiO2 + 2C→Ndi + 2CO

Chiyero cha silicon chopezedwa motere ndi 97 ~ 98%, chomwe chimatchedwa silicon yachitsulo.Ndiye amasungunuka ndi kukonzanso, ndipo zonyansa zimachotsedwa ndi asidi kuti zipeze zitsulo zachitsulo ndi chiyero cha 99.7 ~ 99.8%.

Mapangidwe a zitsulo zachitsulo ndi silicon, choncho ali ndi zofanana ndi silicon.
Silicon ili ndi ma allotropes awiri:silicon ya amorphous ndi crystalline silicon.

Silicon ya amorphous ndiimvi-wakuda ufakuti kwenikweni ndi microcrystal.

Silicon ya crystalline ili ndikapangidwe ka kristalondisemiconductor katundu wa diamondi, ndimalo osungunuka ndi 1410 ° C, malo otentha ndi 2355 ° C, kuuma kwa Moh ndi 7, ndipo ndi brittle.Silicon ya amorphous imakhala yogwira ntchito ndipo imathakuyaka mwamphamvu mu oxygen.Imakhudzidwa ndi zinthu zopanda zitsulo monga halogen, nayitrogeni ndi carbon pa kutentha kwakukulu, ndipo zimatha kuyanjananso ndi zitsulo monga magnesium, calcium ndi iron kupanga ma silicides.Amorphous silikoni pafupifupi insoluble mu zonse inorganic ndi organic zidulo kuphatikizapo hydrofluoric acid, koma sungunuka zidulo osakaniza wa nitric acid ndi hydrofluoric acid.Njira yothetsera sodium hydroxide imatha kusungunula silicon ya amorphous ndikutulutsa haidrojeni.Crystalline pakachitsulo ndi wosagwira ntchito, zilibe kuphatikiza ndi mpweya ngakhale kutentha kwambiri, ndi insoluble mu asidi inorganic ndi asidi organic, koma sungunuka zidulo osakaniza wa nitric acid ndi hydrofluoric acid ndi anaikira sodium hydroxide njira.

Kuchuluka kwa silicon kumagwiritsidwa ntchito posungunula mu aloyi ya ferrosilicon monga chinthu chophatikizira mumakampani achitsulo ndi zitsulo, komanso ngati chochepetsera pakusungunula zitsulo zamitundu yambiri.Silicon ndi gawo labwino muzitsulo za aluminiyamu, ndipo ma aloyi ambiri opangidwa ndi aluminiyamu amakhala ndi silicon.
