3303,441,553 silicon simbi yekuwedzera yealuminium alloy casting

Indasitiri, simbi silicon inowanzogadzirwa nekudzikisa silica nekabhoni muchoto chemagetsi.

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

Kuchena kwesilicon kunowanikwa nenzira iyi 97 ~ 98%, iyo inonzi metal silicon.Iyo inobva yanyungudutswa uye yakadzokororwa, uye tsvina inobviswa neasidhi kuti iwane metallic silicon nekuchena kwe99.7 ~ 99.8%.

Kuumbwa kwesimbi silicon inonyanya kuve silicon, saka ine zvinhu zvakafanana kune silicon.
Silicon ine maviri allotropes:amorphous silicon uye crystalline silicon.

Amorphous silicon ndeyegrey-black powderizvo chaizvoizvo microcrystal.

Crystalline silicon ine iyochimiro chekristarouyesemiconductor zvimiro zvedhaimondi, ivokunyungudika i1410°C, nzvimbo yekubikira i2355 ° C, kuoma kweMoh ndeye 7, uye ine brittle.Amorphous silicon inoshanda nemakemikari uye inogonakupisa nechisimba muokisijeni.Inopindirana nezvisiri-simbi zvakaita sehalogen, nitrogen uye kabhoni pakupisa kwepamusoro, uye inogonawo kudyidzana nesimbi senge magnesium, calcium uye iron kugadzira silicides.Amorphous silicon inenge isinganyungudike mune ese inorganic uye organic acids kusanganisira hydrofluoric acid, asi inonyungudika mumisanganiswa asidhi yenitric acid uye hydrofluoric acid.Yakagadziriswa sodium hydroxide mhinduro inogona kunyungudutsa amorphous silicon uye kuburitsa hydrogen.Crystalline silicon haisati yashanda, haisanganisi neokisijeni kunyangwe pakupisa kwakanyanya, hainyungudika mune chero inorganic asidhi uye organic acid, asi inonyungudika mumisanganiswa asidhi yenitric acid uye hydrofluoric acid uye concentrated sodium hydroxide solution.

Huwandu hukuru hwesilicon hunoshandiswa kunyungudutsa muferrosilicon alloy sechinhu chinosanganisa muindasitiri yesimbi nesimbi, uye sechinhu chinoderedza mukunyungudutsa marudzi mazhinji esimbi.Silicon zvakare chinhu chakanaka mualuminium alloys, uye akawanda akakandwa aruminiyamu alloys ane silicon.
