Hauv ntau daim ntawv thov kev lag luam kub siab, crucibles ua lub luag haujlwm tseem ceeb uas yog cov ntim khoom tseem ceeb rau kev tuav thiab cov khoom cua sov.Silicon carbide ceramic crucibles, nrog lawv cov kev ua tau zoo heev, maj mam dhau los ua qhov kev xaiv zoo tshaj plaws hauv ntau qhov kev lag luam.
1, Dab tsi yog silicon carbide ceramic crucible
Silicon carbide ceramic crucible yog lub tais tob hauv qab zoo li lub thawv uas yog ua los ntawm silicon carbide ceramic khoom. Silicon carbide yog ib qho kev sib txuas nrog cov khoom sib txuas uas muaj zog, thiab nws cov khoom siv tshuaj lom neeg tshwj xeeb ua rau cov crucibles nrog ntau yam khoom zoo heev. Piv nrog rau cov iav iav, silicon carbide ceramic crucibles tuaj yeem tiv taus qhov kub thiab txias thiab yog cov cuab yeej zoo tshaj plaws rau kev ua haujlwm kub kub.
2, Qhov zoo ntawm Silicon Carbide Ceramic Crucibles
1. Kev kub siab ua haujlwm zoo: Silicon carbide ceramic crucibles tuaj yeem tiv taus qhov kub thiab txias txog li 1350 ℃. Lub zog ntawm cov khoom siv ceramic zoo ib yam yuav txo qis ntawm 1200 ℃, thaum lub zog khoov ntawm silicon carbide tseem tuaj yeem khaws cia ntawm qib siab ntawm 1350 ℃. Cov yam ntxwv no ua rau nws ua tau zoo nyob rau hauv high-temperature melting, firing thiab lwm yam txheej txheem, muab ib tug ruaj khov kub-kub ib puag ncig rau cov ntaub ntawv thiab xyuas kom meej cov kev ua tau zoo ntawm cov txheej txheem.
2. Zoo oxidation tsis kam: Silicon carbide ceramic crucibles tuaj yeem tswj tau oxidation zoo nyob rau hauv qhov kub thiab txias. Nrog rau qhov nce ntawm silicon carbide cov ntsiab lus, oxidation kuj ntawm lub crucible yog ntxiv txhim kho. Qhov no txhais tau hais tias nws tsis yooj yim oxidized thiab puas thaum lub sij hawm ntev-kub siv, txuas nws lub neej kev pab cuam, txo qhov zaus ntawm crucible hloov, thiab txo nqi ntau lawm.
3. Cov tshuaj lom neeg ruaj khov zoo heev: Silicon carbide ceramics tiv taus ntau dua rau kev daws teeb meem corrosive. Hauv kev lag luam uas muaj ntau yam tshuaj lom neeg xws li metallurgy thiab chemical engineering, nws tsis hnov mob nrog cov tshuaj lom neeg uas nws los rau hauv kev sib cuag nrog, yog li ua kom cov purity ntawm melted los yog reacted tshuaj, zam kev qhia impurities, thiab txhim kho cov khoom zoo.
4. High hardness thiab hnav tsis kam: Silicon carbide muaj lub siab hardness, uas ua rau cov crucible tsim muaj zoo hnav tsis kam thiab tuaj yeem tiv taus lub cev hnav ntawm qhov kub thiab txias. Thaum siv mus sij hawm ntev, nws tuaj yeem tswj tau qhov kev ncaj ncees ntawm nws cov duab thiab tsis yooj yim hnav lossis deformed, ntxiv kom ntseeg tau nws cov txiaj ntsig thiab kev pabcuam lub neej.
3, Daim ntawv thov teb ntawm silicon carbide ceramic crucibles
1. Kev lag luam metallurgical: Txawm hais tias nws yog kev ua kom zoo ntawm cov hlau ferrous xws li hlau, lossis cov hlau tsis muaj hlau thiab lawv cov alloys xws li tooj liab, txhuas, zinc, thiab lwm yam, silicon carbide ceramic crucibles ua lub luag haujlwm tseem ceeb. Nws tuaj yeem tiv taus qhov yaig ntawm cov kua hlau kub kub, kom ntseeg tau tias kev ua tiav ntawm cov txheej txheem hlau melting, thaum ua kom cov purity ntawm hlau thiab txhim kho cov khoom hlau zoo.
2. Kev lag luam tshuaj lom neeg: siv rau cov tshuaj tiv thaiv kub kub thiab kev kho mob corrosive media. Vim nws cov tshuaj lom neeg ruaj khov zoo heev thiab kub tsis kam, nws tuaj yeem ua haujlwm ruaj khov nyob rau hauv lub ntsej muag ntawm ntau yam tshuaj lom neeg thiab cov tshuaj tiv thaiv kub kub ib puag ncig, kom ntseeg tau tias qhov kev vam meej ntawm cov tshuaj tiv thaiv kab mob thaum tiv thaiv lub crucible nws tus kheej los ntawm corroded thiab puas.
3. Industrial kiln: siv los ua lub thawv cua sov rau kev tua ntau yam khoom siv, xws li cov cib tiv thaiv hluav taws. Los ntawm kev siv nws cov thermal conductivity zoo thiab kub tsis kam, nws tuaj yeem hloov tau sai thiab sib npaug, xyuas kom zoo ntawm cov khoom siv hluav taws xob, thiab txhim kho kev siv hluav taws xob.
Silicon carbide ceramic crucibles, nrog rau cov txiaj ntsig zoo xws li kub tsis kam, oxidation tsis kam, hnav tsis kam, thiab tshuaj lom neeg ruaj khov, tau pom muaj txiaj ntsig zoo hauv ntau qhov kev lag luam thiab yog cov ntim khoom zoo tshaj plaws nyob rau hauv high-temperature industrial field. Nrog rau kev nce qib txuas ntxiv thiab kev tsim kho tshiab ntawm thev naus laus zis, peb ntseeg tias silicon carbide ceramic crucibles yuav siv rau hauv ntau lub teb thiab muab kev txhawb zog rau kev txhim kho ntawm ntau yam kev lag luam.
