Graphite crucible feem ntau yog siv los smelt tooj liab, tooj dag, kub, nyiaj, zinc thiab txhuas, thiab lwm yam uas tsis yog-ferrous hlau thiab lawv alloys.
Peb cov graphite crucible tau ua tiav nrog siab purity isostatic pressed graphite, uas muaj thermal conductivity zoo thiab kub tsis kam. Nyob rau hauv tus txheej txheem ntawm kev siv kub kub, lub coefficient ntawm thermal expansion yog me me, thiab nws muaj tej yam strain resistance rau mob kub thiab txias txias.Nws muaj zog corrosion kuj rau acid thiab alkaline kua thiab zoo heev tshuaj stability. Cov qauv tshwj xeeb tuaj yeem hloov kho nrog cov duab kos thiab cov qauv, thiab cov ntaub ntawv yog cov graphite hauv tsev thiab cov graphite tuaj yeem ua tau raws li qhov sib txawv ntawm cov neeg siv khoom.
Cov ntaub ntawv tseem ceeb ntawm graphite crucible yog graphite, silicon carbide, silica, refractory av nplaum, suab, thiab tar, thiab lwm yam.
