Silicon Carbide hmoov
SiC hmoov Kev piav qhia
Silicon carbide hmoov yog silicon carbide pub qhov chaw uas tsis muaj impurity cov ntsiab lus thiab cov khoom me me uas yuav tsum tau ua rau kev npaj siab - zoo silicon carbide ib leeg siv lead ua, tshwj xeeb tshaj yog nyob rau hauv kev npaj siab - purity semi- insulating silicon carbide los yog doped semi- insulating silicon carbide qib siab, uas yuav tsum tau muaj cov ntsiab lus siab heev.
Thaum cov khoom siv silicon carbide muaj cov impurities, tshwj xeeb tshaj yog lub zog qis impurities (xws li cov ntsiab lus nitrogen), nws nyuaj heev rau kev tshem tawm hauv cov txheej txheem tsim khoom, yog li thaum cov khoom siv muaj ntau cov impurities, nws tsis tuaj yeem ua tiav qhov kev tsim khoom siab -purity semi- insulating silicon carbide khoom qhov chaw. Tsis tas li ntawd, cov particle loj uniformity ntawm cov hmoov synthesized yog tsawg, thiab lub hom phiaj particle loj piv ntawm silicon carbide hmoov yog me me.

Ib txoj hauv kev los npaj ib qho qis-nqi huab hwm coj-producible siab-purity silicon carbide hmoov, suav nrog cov kauj ruam hauv qab no:
Purifying cov cuab yeej npaj rau kev npaj silicon nitride hmoov, npaj cov khoom siv raw, thiab tom qab ntawd sib tov cov hmoov carbon thiab silicon hmoov kom tau cov hmoov sib tov; Muab cov hmoov sib tov rau hauv ib lub crucible, thiab tom qab ntxuav lub qhov cub nrog sib tov ntawm argon thiab hydrogen, sintering yog nqa tawm nyob rau hauv cov kev mob ntawm ib tug sib tov ntawm argon thiab hydrogen kom tau lub siab - purity silicon carbide hmoov.
Cov hmoov silicon yog purified los ntawm kev kho cua sov, hais tias kev kho cua sov yog raws li nram no: lub cub tawg siab yog tswj ntawm 10 kpa mus rau 80 kpa; nyob rau hauv tus nqi ntws ntawm argon roj yog 50 mus rau 500 sccm thiab hydrogen gas yog 50 mus rau 500 sccm; thiab qhov kub thiab txias yog nce los ntawm chav tsev kub mus rau 900℃ntawm tus nqi ntawm 2 mus rau 10℃/ min. Tuav ntawm 900 degree, rauv siab ntawm 10kpa txog 80kpa, argon roj ntawm 50 mus rau 500sccm, hydrogen gas ntawm 0 txog 500sccm rau 10 mus rau 80 teev; cov pa roj carbon monoxide yog purified los ntawm kev kho cua sov, hais tias kev kho cua sov yog raws li nram no: tuav lub cub tawg siab ntawm 10kpa mus rau 80kpa, lees argon roj ntawm 100 mus rau 600sccm thiab hydrogen roj ntawm 10 mus rau 300sccm, thiab nce qhov kub ntawm 3 mus rau 10℃/ min cua sov tus nqi ntawm 1 20 ° C rau 1 20℃qhov kub thiab txias. tuav 5 ~ 30 teev; Tom qab ntawd txuas ntxiv nce qhov kub thiab txias, nyob rau hauv 1900 ~ 2200℃tej yam kev mob, siab 1 ~ 50kpa, argon 100 ~ 600sccm, hydrogen 10 ~ 300sccm tej yam kev mob los tswj 10 ~ 60 teev; txias cia qhov kub thiab txias ua ntej lub siab yog nce mus rau 80 ~ 95kpa, los ntawm argon 100 ~ 600sccm, hydrogen 100 ~ 500sccm, thiab ces yuav mus rau 40 ~ 80 degree; kom txo qis rau 40 ~ 80 degree, qhib lub cub tawg ntawm lub qhov tshwj tseg, ntxiv viscosity ntawm 1 ~ 5cps ntawm silicone roj, nyob rau saum npoo ntawm cov pa roj carbon monoxide los tsim cov yeeb yaj kiab tiv thaiv. Cov molar piv ntawm carbon hmoov thiab silicon hmoov yog (0.9 rau 1.1): 1; Hauv cov roj sib xyaw ntawm argon thiab hydrogen, qhov ntim piv ntawm argon rau hydrogen yog 10: 1 txog 1: 10.
Silicon carbide hmoov sintering txoj kev yog:nyob rau hauv 20kpa ~ 80kpa siab tej yam kev mob, kis mus rau hauv lub hydrogen 50 ~ 300sccm, argon 400 ~ 1000sccm, qhov kub yuav nce mus rau 1600 ~ 1800 degree, rau 4 ~ 20 teev; yuav txo qhov siab mus rau 1kpa ~ 50kpa, dhau mus rau hydrogen 20 ~ 200sccm, argon 200 ~ 600sccm Qhov kub yog nce mus rau 1900-2300℃rau 10-50 teev. Cov khoom siv sintered tau txais tom qab sintering yog crushed thiab graded kom tau high-purity silicon carbide hmoov.

FAQ
Q: Koj ua li cas kho qhov kev tsis txaus siab zoo?
A: Ua ntej tshaj plaws, peb qhov kev tswj xyuas zoo yuav txo qhov teeb meem zoo rau zero. Nyob rau hauv rooj plaub muaj teeb meem zoo tiag tiag tshwm sim los ntawm peb, peb yuav xa cov khoom dawb rau koj los hloov lossis rov qab koj cov nyiaj poob.
Q: Koj puas muaj kev tswj xyuas zoo?
A: Yog, peb tau txais BV, SGS authentication.
Q: Koj lub sijhawm xa khoom ntev npaum li cas?
A: Feem ntau nws yog 7-14 hnub yog tias cov khoom muaj nyob hauv Tshuag. los yog nws yog 25-45 hnub yog tias cov khoom tsis nyob hauv Tshuag, nws yog raws li kom muaj nuj nqis.
Q: Peb puas tuaj yeem tau txais qee cov qauv ntawm Silicon Carbide Powder ? Muaj nqi?
A: Yog lawm, peb tuaj yeem muab cov qauv dawb tab sis tsis them tus nqi thauj khoom. Yog tias koj tso qhov kev txiav txim tom qab paub meej cov qauv, peb yuav rov qab koj cov khoom xa tuaj los yog txiav tawm ntawm tus nqi xaj.
