Lub cev muaj zog ntawm Silicon Hlau Hmoov
(1) Kev Purity High & Composition
Raug purity: ranges los ntawm 98% rau 99. 9999% (6n), nrog impurities (FE, QIB AS CURIOR nce.
Cuam tshuam: kev coj dawb huv siab dua txhim kho kev ua tau zoo hauv cov khoom siv hluav taws xob thiab cov hlwb hlwb .
(2) Qhov loj me me & morphology
Loj npaum li cas: los ntawm ntxhib (150-2000 μm) rau ultrafine / nano (<10 µm or <100 nm).
Morphology:
Angular hais (milled hmoov) - zoo dua rau cov sib txuas sib txuas metallurgical .
Kheej kheej (atomized hmoov) - txhim kho Flowability rau 3D luam ntawv .
Kev Cuam Tshuam: Finer hmoov nce reactivity thiab thaj chaw nto, tseem ceeb rau roj thiab tshuaj lom .
(3) Qiv & Melting point
Qhov ceev faj: ~ 2 {. 33 g / cmless (qis dua cov hlau zoo li hlau, muaj txiaj ntsig rau lub tsho alloys).
Melting taw tes: 1,414 degree, ua rau nws ruaj khov nyob rau hauv cov kev siv kub siab (e {} g., reciet}
Tshuaj Kho Mob Ntawm Silicon Hlau Hmoov
(1) cov kev siv hluav taws xob siab
Reacts nrog oxygen (cov txheej txheej sio₂), halogens (e {{}}, chlorine rau sicl₄), thiab alkalis {2}
Cuam tshuam: Qhov tseem ceeb rau Silicone ntau lawm thiab cov tshuaj synthesis .
(2) oxidation tsis kam
Ua cov txheej txheem passive sio₂ txheej nyob rau hauv huab cua, tiv thaiv ntxiv corrosion .
Kev cuam tshuam: Txhim kho cov kev ua kom ruaj khov hauv cov alloys thiab cov txheej txheem .
(3) tus cwj pwm ncaj qha
Intrinsic Silicon tau muaj kev cuam tshuam tsawg, tab sis doping (b, p) hloov nws cov hluav taws xob {}}
Cuam tshuam: lub hauv paus rau cov khoom siv hluav taws xob thiab lub hlwb hlwb .
Ua haujlwm zoo ntawm cov silicon hlau hmoov
(1) alloy alloy ntxiv dag zog
Txhim kho hardness, hnav tsis kam, thiab Tsoom Fwv hauv Al-Si thiab Fe-Si alloys.}}
Piv txwv: Pistousive pistons ua los ntawm si-nplua nuj txhuas alloys .
(2) thermal & kev ua hluav taws xob
Siab high thermal conductivity (~ 150 w / min k · k) - muaj txiaj ntsig hauv cov khoom kub-resistant .
Hloov tau resistivity (ntawm doping) - tseem ceeb rau semiconductors .
(3) lub teeb yuag & lub zog siab
Silicon-rechnovered composites muab cov kev sib zog ua kom muaj zog-rau-hnyav piv, zoo tagnrho rau aerospace {}}
