High Silicon Carbon

Dab tsi yog High Carbon Silicon?

 

 

Cov pa roj carbon ntau yog hais txog silicon carbon alloy nrog qhov sib piv ntawm cov pa roj carbon thiab silicon ntau dua 1: 1, feem ntau yog nyob rau hauv daim ntawv ntawm SiC. Piv nrog cov pa roj carbon tsawg, cov roj carbon silicon siab dua hardness, melting point thiab tshuaj stability, nrog rau zoo heev thermal conductivity thiab hluav taws xob rwb thaiv tsev zog.

Nws yog ib qho tseem ceeb siv nyob rau hauv foundries. Raws li koj paub cov hlau cam khwb cia muaj C: 2-4%, Si: 1-3%, thiab Carbon thiab silicon yog cov ntsiab lus tseem ceeb cuam tshuam rau microstructure ntawm cam khwb cia hlau. High Carbon Silicon tau ua carbon alloyed hauv nws, yog li nws tuaj yeem muab ob lub ntsiab lus zoo. Tsis ntev los no nws kuj tau siv rau hauv kev tsim steel, tshwj xeeb tshaj yog steel scraps melting. Nws ua hauj lwm ua deoxidizer thiab ua kom muaj cua sov (Si&C: 6.58kcal / g, 1.24kcal / g txhua) thiab recarburizer. Nrog Si & C tsawg kawg yog 90%, qhov impurity tsawg heev, yog li cov tswv yim yooj yim los tswj.

Cov txheej txheem kev npaj ntawm cov pa roj carbon silicon feem ntau suav nrog lub cev vapor deposition (PVD), tshuaj vapor deposition (CVD) thiab mechanical alloying (MA). Ntawm lawv, PVD thiab CVD txoj kev tuaj yeem ua tiav thaj chaw loj ntawm cov pa roj carbon ntau silicon films, thaum MA txoj kev tsim nyog rau kev npaj high-purity high-carbon silicon hmoov. Cov qauv siv lead ua ntawm high-carbon silicon feem ntau suav nrog cov qauv hexagonal (xws li SiC-4H thiab SiC-6H, thiab lwm yam) thiab cubic qauv (xws li SiC-3C, thiab lwm yam. ). High-carbon silicon nrog cov qauv sib txawv muaj qhov sib txawv ntawm lub cev thiab tshuaj lom neeg. High-carbon silicon muaj cov yam ntxwv ntawm siab hardness, siab melting point thiab siab thermal conductivity. Nws qhov hardness tuaj yeem ncav cuag Mohs qib 9, nws cov ntsiab lus melting yog siab dua 2700 degree, thiab nws cov thermal conductivity tuaj yeem ncav cuag 20W / m·K. Tsis tas li ntawd, high-carbon silicon kuj muaj cov khoom siv hluav taws xob zoo heev thiab kev ruaj ntseg tshuaj.

1. Vim tias cov pa roj carbon ntau silicon muaj cov khoom zoo ntawm lub cev thiab tshuaj lom neeg ruaj khov, nws muaj cov ntawv thov dav dav hauv thaj chaw hluav taws xob. Piv txwv li, high-carbon silicon tuaj yeem siv los tsim cov khoom siv hluav taws xob kub, siab zaus thiab siab zog, xws li cov khoom siv hluav taws xob hluav taws xob, cov khoom siv microwave thiab lasers.
2. High-carbon silicon kuj tseem muaj cov ntawv thov tseem ceeb hauv thaj chaw ntawm optoelectronics. Siv nws cov yam ntxwv dav dav, silicon carbon siab tuaj yeem siv los tsim cov khoom siv hluav taws xob zoo, kub-resistant optoelectronic, xws li high-speed optical modulators, high-temperature lasers, thiab high-sensitivity photodetectors.
3. High-carbon silicon muaj cov thermal conductivity zoo thiab hluav taws xob rwb thaiv tsev, yog li nws kuj muaj cov ntawv thov tseem ceeb hauv microwave teb. Piv txwv li, high-carbon silicon tuaj yeem siv los tsim cov khoom siv hluav taws xob kub, siab zaus microwave, xws li lub zog amplifiers, mixers, thiab lim.

Raw khoom npaj: Cov ntaub ntawv tseem ceeb ntawm silicon-carbon alloy yog silicon thiab carbon. Silicon feem ntau siv smelting quartz ore kom tau txais high-purity metallic silicon; carbon feem ntau siv cov khoom xws li coke thiab graphite.

Sib tov thiab proportioning: Sib tov cov khoom siv ntshiab silicon thiab cov khoom siv carbon raws li qhov sib piv, thiab ntxiv qhov tsim nyog ntawm flux thiab additives. Cov txheej txheem sib xyaw ua kom ntseeg tau tias cov khoom siv raw yog tag nrho thiab sib npaug sib xyaw kom ntseeg tau tias qhov sib xws thiab ruaj khov ntawm cov txheej txheem smelting tom ntej.

Charge refining: Muab cov khoom sib tov rau hauv lub qhov cub hluav taws xob tshwj xeeb lossis lub qhov cub kom kub kub smelting. Thaum lub sij hawm smelting txheej txheem, los ntawm kev tswj cua sov thiab kev txiav txim ntawm kev txo cov neeg ua hauj, cov hlau silicon nyob rau hauv cov sib tov reacts nrog carbonization los tsim ib tug silicon-carbon alloy. Qhov kub thiab txias, lub sijhawm thiab lwm yam txheej txheem yuav tsum tau tswj hwm kom tau txais txiaj ntsig zoo tshaj plaws smelting.

Refining thiab purification: Cov silicon-carbon alloy tau los ntawm smelting kuj tseem muaj qee yam impurities thiab yuav tsum tau ua kom zoo thiab ua kom huv. Cov txheej txheem refining muaj xws li slag tshem tawm, deoxidation thiab sulfur tshem tawm los txhim kho lub purity thiab kev ua tau zoo ntawm cov hlau.

Tsim thiab ua: Cov silicon-carbon alloy uas tau ua kom huv thiab huv tuaj yeem tsim thiab ua tiav. Nyob ntawm cov kev xav tau tshwj xeeb, silicon-carbon alloys tuaj yeem npaj rau hauv cov khoom sib txawv thiab ntau thiab tsawg los ntawm cov txheej txheem xws li nias, sintering, casting thiab ua.

Kev tswj kom zoo: Hauv kev tsim cov txheej txheem ntawm silicon-carbon alloy, kev tswj kom zoo yog qhov tseem ceeb heev. Los ntawm kev sim cov txheej txheem xws li tshuaj ntsuam xyuas, ntsuas kev ua haujlwm ntawm lub cev thiab metallographic microscopy, peb xyuas kom meej tias qhov muaj pes tsawg leeg thiab kev ua haujlwm ntawm cov khoom ua tau raws li cov qauv xav tau.
