Hauv tsab xov xwm no, peb yuav piav qhia txog cov yam ntxwv tseem ceeb, kev siv, kev siv cov lus qhia, thiab kev ceev faj cuam tshuam nrog Sic Crucible, tso lub teeb rau lawv lub luag haujlwm tseem ceeb hauv kev tshawb fawb thiab kev lag luam.

I. Nkag siab txog Silicon Carbide Crucibles

Silicon Carbide Casting Crucible yog cov nkoj dav siv hauv chav kuaj thiab chaw tsim khoom rau lawv lub peev xwm los tiv taus kub kub, corrosive, thiab abrasive tej yam kev mob. Lawv cov yam ntxwv tseem ceeb muaj xws li:

Tshwj xeeb Thaum tshav kub kub Resistance: Silicon Carbide Crucible boasting ib tug impressive tshav kub tsis kam, muaj peev xwm tiv taus kub tshaj 2000 ° C. Cov cuab yeej no ua rau lawv tsim nyog rau kev sim uas muaj cov ntaub ntawv kub-siab kub thiab tshuaj reagents.

Chemical Inertness: Cov Sic Graphite Crucible muaj cov tshuaj inertness, kom ntseeg tau tias lawv tsis hnov ​​​​mob nrog cov tshuaj uas lawv muaj, ua rau lawv zoo tagnrho rau ntau yam kev sim tshuaj.

Hluav taws xob rwb thaiv tsev: Silicon carbide crucibles muaj cov khoom siv hluav taws xob zoo heev, ua rau lawv muaj txiaj ntsig zoo hauv kev siv hluav taws xob uas yuav tsum tau txo qis.

High Thermal Conductivity: Lawv cov thermal conductivity zoo ua kom cov cua sov tsis sib xws thiab tswj qhov kub thiab txias thaum sim.

II. Kev siv ntau yam

Smelting Crucibles pom ntau yam kev siv:

Kev Siv Tshuaj: Hauv cov chaw kuaj tshuaj, lawv feem ntau siv rau kev kub ntxhov thiab kev sim xws li cov qauv fusion, melting tshwj xeeb iav fibers, thiab kho fused quartz. Lawv kuj yog cov cuab yeej siv hauv casting, sintering, thiab kev kho cua sov.

Kev Siv Hluav Taws Xob: Kev lag luam xws li steel ntau lawm, hlau tsim, semiconductor ua, thiab polymer cov ntaub ntawv fabrication cia siab rau ntau ntawm silicon carbide crucibles. Cov crucibles no yog qhov tseem ceeb rau kev siv kub kub thiab kev ua cov khoom siv.

III. Cov txheej txheem siv kom raug

Rau kev ua tau zoo thiab kev ua haujlwm ntev, nws yog ib qho tseem ceeb kom ua raws li cov lus qhia tshwj xeeb thaum ua haujlwm nrog silicon carbide crucibles:

Preheating: Ntxuav lub crucible kom huv si thiab preheat nws nyob rau hauv 200 ° C-300 ° C ntau li 2-3 teev kom tshem tawm tej impurities thiab noo noo, tiv thaiv thermal shock-induced puas.

Chaw thau khoom: xyuas kom meej tias cov khoom yuav tsum tau ua tiav tsis pub dhau lub crucible lub peev xwm, tso cai rau cov huab cua kom zoo thiab cov tshuaj tsis sib xws.

Cua sov: Muab lub crucible tso rau hauv lub tshuab cua sov, ua tib zoo saib xyuas qhov ntsuas kub thiab ntsuas kub.

Txias: Tom qab cua sov ua tiav, tso cai rau lub qhov cub kom txias rau chav sov ua ntej tshem cov silicon carbide crucible.

Ntxuav: Tam sim ntawd ntxuav lub crucible tom qab siv kom tsis txhob muaj cov tshuaj residual los yog tshuaj thaum siv yav tom ntej.

IV. Cov kev ceev faj

Txhawm rau ua kom lub neej ntev thiab ua tau zoo ntawm silicon carbide crucibles, nws yog ib qho tseem ceeb uas yuav tau xav txog cov kev ceev faj:

Kov nrog Kev Saib Xyuas: Silicon carbide yog cov khoom siv tawv tawv, yog li tuav cov crucibles maj mam kom tsis txhob chipping lossis tawg vim muaj kev cuam tshuam.

Khaws huv thiab qhuav: Khaws cov crucibles kom huv si thiab qhuav kom tsis txhob muaj kab mob thiab impurities nkag mus.

Compatibility: Xyuas kom meej tias qhov kev xaiv ntawm crucible yog sib xws nrog cov tshuaj tshwj xeeb lossis cov khoom siv rau qhov kev sim zoo tshaj plaws.

Temperature Control: Tswj qhov kub thiab txias thaum lub sij hawm cua sov kom tsis txhob overheating los yog txias ceev.

Kev pov tseg kom zoo: pov tseg cov khoom siv silicon carbide crucibles raws li cov kev cai ib puag ncig los tiv thaiv kev ua qias tuaj ib puag ncig.

Hauv kev xausn: silicon carbide crucibles yog ib qho tseem ceeb ntawm kev kuaj thiab cov hlab ntsha, muab cov kav ntev thiab kev ntseeg siab uas xav tau rau ntau yam kev siv kub kub. Ua raws li kev siv kom raug thiab kev tiv thaiv kev tiv thaiv kom lawv lub neej ntev thiab txhim kho lawv txoj kev koom tes rau kev ua haujlwm zoo ntawm chav kuaj thiab cov txheej txheem kev lag luam.
