Crucible daws: Cov thev naus laus zis rau cov khoom siv science thiab muaj kev lag luam

Crucibles yog cov tseem ceeb uas siv nyob rau hauv high - kub yaj, tshuaj lom neeg npaj khoom siv. Lawv cov kev ua tau zoo ncaj qha cuam tshuam cov khoom zoo thiab ntau lawm kev ua tau zoo. Nrog qhov nce zuj zus rau qhov siab nce rau high- cov txheej txheem kub, ua kom zoo cov kev daws teeb meem tau dhau los ua cov ntaub ntawv tseem ceeb hauv cov khoom siv science.

Tsoos cov cruciles feem ntau yog ua los ntawm graphite, quartz, lossis cov kev txwv, tab sis cov kev txwv, tab sis cov no} kub ruaj khov, thiab kev pabcuam lub neej. Tsis ntev los no tsim tawm hauv high - Cov ntaub ntawv ua tau zoo xws li Silicon Carbide (ZroConium oxide tau txhim kho kev ua kom zoo nkauj crucible. Piv txwv li, silicon carride crucailes tswj cov qauv kev ruaj ntseg hauv qhov kub tshaj 1600 degree, ua rau lawv haum rau cov hlau melting thiab semiconductor khoom npaj. Zirconia crucibles, txawm li cas los xij, puas yog qhov kev xaiv uas xav tau rau precision Melting kev sim hauv lub chaw soj ntsuam vim lawv cov tshuaj inertness.

Crucible kev daws yuav tsum yog tsim nrog kev ua haujlwm hauv siab rau ntau yam kev thov sau cov xwm txheej. Piv txwv li, hauv kev lag luam metallurgical, crucibles xav tau tshwj xeeb cov txheej tshwj xeeb kom txo cov hlau nkag mus. Hauv kev lag luam photovoltaic, crucobles rau polysilicon ingot ingot ingot casting yuav tsum muaj siab- purity cov ntaub ntawv kom tiv thaiv kev paug impurity. Tsis tas li ntawd, kev qhia ntawm cov qauv tsim qauv thiab nrawm- hloov cov tshuab txuas ntxiv txo qis qis qis thiab kev txij nkawm cov nqi hauv kev lag luam.

Nyob rau hauv lub neej yav tom ntej, kev txhim kho cov tshuab crucible yuav ceeb toom rau kev loj hlob ntse thiab ntsuab. Los ntawm kev sib xyaw ua ke ntsuas kub nrog cov tshuaj xyuas kev tswj hwm, tiag- Lub sijhawm cov ntaub ntawv tawm tswv yim tuaj yeem ua kom pom cov txheej txheem melting. Tsis tas li ntawd, kev txhim kho ntawm cov phooj ywg ib puag ncig refractory yuav txo cov khib nyiab muaj kuab khib nyiab. Los ntawm kev sib xyaw ua haujlwm hauv cov ntaub ntawv kev tshawb fawb, thermodynamics, thiab kev daws teeb meem ntse yuav txuas ntxiv kom muaj txiaj ntsig zoo thiab txhim khu kev lag luam kom muaj kev lag luam siab.
