Cov khoom siv graphite xaiv muaj cov yam ntxwv hauv qab no:
1.Kev kub siab ua haujlwm: siab refractoriness, qhov siab tshaj plaws kub tuaj yeem ncav cuag li 2000 degree.
2. Thermal stability: Lub hom phiaj ntawm kev siv cov cua kub ceev thiab txias ntawm graphite crucible, tshwj xeeb tsim yog nqa tawm kom ntseeg tau tias cov khoom zoo.
3.Corrosion kuj: Cov qauv tsim thiab zoo matrix ncua kev corrosion ntawm crucible.
4.Impact resistance: Graphite crucible tuaj yeem tiv taus siab thermal shock zog, yog li txhua tus txheej txheem tuaj yeem ua tiav nrog kev ntseeg siab.
5. Acid kuj: Qhov sib ntxiv ntawm cov ntaub ntawv tshwj xeeb tuaj yeem txhim kho qhov zoo ntawm lub crucible, ua tau zoo nyob rau hauv cov ntsuas acid tiv thaiv, thiab ua kom ntev lub neej kev pab cuam ntawm graphite crucible.
6.High thermal conductivity: Cov ntsiab lus siab ntawm cov pa roj carbon monoxide ua kom zoo thermal conductivity, txo lub sij hawm tawg, thiab txo qis zog noj.
7. Kev tswj cov hlau tsis huv: Kev tswj xyuas nruj ntawm cov khoom sib xyaw ua kom ntseeg tau tias cov graphite crucible tsis paug cov hlau thaum tawg.
8. Kev ruaj ntseg zoo: Cov cuab yeej siv hluav taws xob ntau ntawm cov txheej txheem kev ua haujlwm siab ua kom muaj kev ruaj ntseg zoo.
9.Anti-adhesion: Vim tias graphite muaj cov cuab yeej tsis yooj yim ua rau cov kua molten, cov kua molten muaj tsawg nkag thiab adhesion.
Peb lub tuam txhab tuaj yeem tsim thiab ua cov graphite crucibles ntawm ntau yam tshwj xeeb raws li cov neeg siv xav tau thiab kos duab.
