Silicon carbide ceramic crucible

Hauv cov lag luam xws li metallurgy, chemical engineering, thiab lub zog tshiab, muaj ib lub thawv uas zoo li tsis tseem ceeb tab sis tseem ceeb heev - lub crucible. Yog tias cov crucibles ib txwm zoo li "cov tais mov hlau", cescov khoom siv silicon carbide ceramic cruciblesyog cov qauv hloov kho tshiab ntawm "titanium alloy tiv thaiv npog". Raws li "tus phab ej tom qab qhov xwm txheej" ntawm kev lag luam niaj hnub no, lub thawv siv lead ua dub no tau txhais dua cov qauv kev nyab xeeb rau kev ua haujlwm kub siab.
Kev Txhais Lus 'Black Technology': Lub Ntuj Tsim ntawm Silicon Carbide
Silicon carbide (SiC), ua lub hauv paus tseem ceeb ntawm cov ntaub ntawv semiconductor tiam peb, kuj qhia txog lub peev xwm zoo kawg nkaus hauv kev ua cov khoom siv ceramics. Cov khoom siv superhard uas tau tsim los ntawm cov khoom siv no muaj cov qauv atomic zoo ib yam li lub pob zeb diamond lattice uas tau tsim tshwj xeeb, ua rau cov khoom siv no muaj peb qhov zoo: tiv taus qhov kub siab tshaj 1350 ℃ yam tsis hloov xim, yooj yim tiv taus cov xov xwm corrosive, thiab hloov pauv cua sov zoo ib yam li cov hlau conductors. Qhov kev tiv thaiv peb-seem ntawm "kev tiv taus cua sov + kev tiv taus corrosion + kev coj ua thermal" no tso cov hlau ib txwm lossis graphite crucibles deb tom qab.

Lub Hwj Chim Ntuj: Cov Kev Ua Rau Muaj Kev Kub Ntxhov Hauv Cov Xwm Txheej Kev Lag Luam
Nyob rau hauv cov xwm txheej ua haujlwm hnyav, silicon carbide ceramic crucibles qhia tau tias muaj kev ruaj khov zoo kawg nkaus. Hauv lub chaw ua haujlwm metallurgical, nws tuaj yeem tswj tau qhov kub siab heev yooj yim; Hauv cov tshuaj lom neeg, nws tseem tsis txav mus rau hauv qhov chaw corrosive heev; Hauv lub chaw kuaj hluav taws xob tshiab, nws cov thermal conductivity sib xws ua kom ntseeg tau tias qhov tseeb ntawm cov khoom siv synthesis. Qhov tsis tshua muaj yog tias lub 'pob zeb diamond tsis puas tsuaj' no tuaj yeem siv dua, txo qhov zaus ntawm kev hloov khoom siv.
Kev Xaiv Ntse: Tus Nqi Ntev Uas Pom Tau
Kev xaiv lub silicon carbide ceramic crucible yog qhov tseem ceeb xaiv kev txawj ntse hauv kev lag luam. Txawm hais tias kev nqis peev thawj zaug yog me ntsis siab dua li cov ntaub ntawv ib txwm muaj, nws qhov kev ua tau zoo ntev thiab ruaj khov tuaj yeem zam cov nqi zais xws li kev cuam tshuam kev tsim khoom thiab kev ua qias tuaj ntawm cov khoom siv raw. Thaum feem ntau cov thawv qhia cov cim ntawm kev qaug zog ntawm qhov kub siab, silicon carbide ceramic crucibles tseem khaws lawv qhov tseeb geometric thawj zaug, thiab qhov "ntev ntev" no yog qhov zoo tshaj plaws hauv kev lag luam niaj hnub no.
Shandong Zhongpeng tau koom nrog tob hauv kev lag luam ntawm silicon carbide ceramics tau ntau xyoo, txuas ntxiv txhim kho cov khoom siv los ntawm cov txheej txheem tshiab, ua rau txhua lub crucible ua tus khub lag luam ntseeg siab. Ntawm txoj kev nrhiav kev ua haujlwm zoo tshaj plaws thiab kev nyab xeeb, silicon carbide ceramics tab tom sau tus qauv tshiab rau cov thawv ntim khoom lag luam niaj hnub nrog lawv "lub zog tawv".
