Hauv kev lag luam metallurgical, kev lag luam graphite crucibles tau ua tiav hauv cov tooj liab ore purification vim lawv cov thermal stability. Los ntawm kev sim tiag tiag, lawv tswj hwm kev ncaj ncees ntawm qhov kub ntawm 2500 degree, thiab tuaj yeem siv txog li 500 zaug (piv rau tsuas yog 100 zaug rau cov khoom siv hlau tsoos), txo cov nqi hloov khoom siv thiab sijhawm poob.
Nyob rau hauv lub tshav pob ntawm synthesizing cov ntaub ntawv tshwj xeeb, xws li carbon nanotube ntau lawm, thermal expansion coefficient ntawm industrial graphite crucibles yog tsawg li 1.2 × 10⁻⁶ / degree, kom ntseeg tau cov uniformity ntawm cov tshuaj tiv thaiv. Cov ntaub ntawv ntsuas qhia tau hais tias cov khoom purity tau nce 20%, deb tshaj li 15% ntawm stainless hlau crucibles (cov ntaub ntawv los ntawm 2024 International Smelting Association daim ntawv qhia).
Nyob rau hauv cov tshuaj lom neeg cov tshuaj tiv thaiv scenarios, cov tshuaj inertness ntawm industrial graphite crucibles ua rau lawv haum rau ib puag ncig uas muaj zog acids thiab muaj zog bases. Hauv NASA txoj haujlwm sib koom tes, nws tau siv rau kev sib txuas ntawm aerospace-qib titanium alloys. Tom qab ua tiav 1000℃thermal cycling test, nws tuav lub siab ntev ntawm ± 0.05mm, ua kom pom nws lub sijhawm ntev - kev cia siab nyob rau hauv cov xwm txheej hnyav.
Kev xaiv cov graphite crucibles muaj peev xwm txhais tau tias xaiv qhov ua tau zoo thiab ntev ntev - kev daws teeb meem rau smelting thiab synthesis. Peb siv cov ntaub ntawv- tsav txoj hauv kev los txhawb koj txoj kev hloov pauv kev lag luam.
