Muaj ntau qhov sib txawv ntawmSilicon Carbide CrucailesThiab graphite cruciles nyob rau ntau yam xws li cov ntaub ntawv xws li cov ntaub ntawv, cov txheej txheem, kev ua tau zoo, thiab tus nqi. Cov kev sib txawv no tsis yog cuam tshuam rau nws cov txheej txheem tsim khoom, tab sis kuj tseem txiav txim siab nws qhov hauj lwm zoo thiab kev tso npe xaiv cov xwm txheej.
ntau qhov sib txawv
Graphite cross yog tsuas yog ua los ntawm ntuj ci graphite thiab siv av nplaum ua ib phau. Qhov kev sib xyaw ua ke no muab cov txheej txheem crucite crucite zoo heev thermal conductivity, ua rau nws haum rau kev siv nyob rau hauv qhov siab kub yaj cov txheej txheem. Tus qauv tshwj xeeb thiab siab thermal conductivity ntawm ntuj flake graphite ua graphite nrov heev nyob rau hauv cov metallurgical thiab tonley Industries.
Silicon Carbide Crucible yog raws li ntuj flake graphite, nrog silicon carbide raws li lub ntsiab tivthaiv thiab kub-resin raws li lub phau ntawv. Raws li Seem me me, Silicon Carbide tau hnav tsis tshua muaj zog thiab thermal ruaj khov, cia silicon carbide crucailes yuav siv nyob rau hauv cov chaw hnyav. Kev siv ntawm cov dej kub siab kuj tseem txhim kho cov crucible lub zog tag nrho thiab lub zog ruaj khov.
Cov txheej txheem sib txawv
Cov txheej txheem tsim ntawm graphite crucible feem ntau yog kev tso cai ntawm phau ntawv thiab tshuab nias. Cov duab me me feem ntau yog tsim los ntawm cov tshuab ua kom zoo nkauj lossis dej noo, ua pov thawj-pov thawj durabiles kom nce durability thiab corrosion tsis kam. Cov txheej txheem ib txwm muaj, thaum muaj txiaj ntsig zoo, muaj kev txwv nyob rau hauv cov nqe lus ntawm kev ua haujlwm thiab zoo sib xws.
Cov txheej txheem ntau lawm ntawm Silicon Carbide Crucible yog qhov sib txawv, siv ietostatic nias cov khoom siv thiab txuj ci. ISostatic nias thev naus laus zis siv cov kev siab siab siab (nce txog 150 MPA), ua rau muaj kev sib txawv siab dua thiab ua tau zoo sib xws thiab sib txawv hauv tus ntoo khaub zig. Tus txheej txheem no tsis yog txhim kho cov crucible ntawm cov tshuab hluav taws xob muaj zog, tab sis kuj tseem ua rau muaj kev tawm tsam cua sov thiab corrosion.
Kev Ua Txawv Sib Txawv
Hais txog kev ua tau zoo, muaj qhov sib txawv ntawm cov teeb meem nkhaus thiab silicon carbide crucailes. Graphite cross muaj qhov ntom ntawm 13 KA / CM², thaum Silicon Carbide crucailes muaj qhov ntom ntawm 1.7 mus rau 26 ka / mm². Qhov kev pabcuam lub neej ntawm Graphite crucibles feem ntau yog 3-5 zaug uas ntawm Silici Carride lub zog thiab corrosion tsis kam ntawm silicon carbide crucaille.
Tsis tas li ntawd, qhov kub sib txawv ntawm sab hauv thiab sab nraud ntawm graphite translucible yog tsuas yog 2-5 degrees, ua kom cov silicon carbide crucle nyob rau hauv cov nqe lus ntawm kev tswj ntsuas kub thiab thermal stability. Cov kua qaub thiab alkali tsis kam thiab corrosion tsis kam ntawm silicon carrides crucailes, uas txhim kho cov zog hluav taws xob thiab txuag tau li 50% lub zog tshaj li graphite crucibles.
Qhov sib txawv hauv nqe
Vim muaj qhov sib txawv hauv cov ntaub ntawv thiab cov txheej txheem tsim khoom, cov teeb meem crucles thiab silicon carbide crucibles kuj muaj qhov tseem ceeb nqe. Feem ntau, silicon carride crucailes yog hais txog peb zaug kim dua li cov ntoo khaub ncaws graphite. Tus nqi no qhia txog qhov tseem ceeb ntawm silicon carbide crucailes nyob rau hauv cov nqe lus ntawm cov khoom raug nqi, kev tsim khoom txheej txheem thiab kev ua haujlwm.
Hauv cov ntsiab lus, txawm hais tias Silicon Carbide CruciLes raug nqi ntau dua, lawv cov khoom lag luam corrosion, thiab lub zog ua tau zoo rau lawv cov ntawv thov xav tau ntau dua. Graphite crucibles nyob twj ywm siv nyob rau hauv ntau daim ntawv thov ua si vim lawv tus nqi qis thiab zoo yooj yim. Qhov kev coj zoo thiab qhov tsis zoo ntawm ob lub crucibes txiav txim siab tias lawv yog qhov tsim nyog rau kev thov sib txawv.
