Graphite crucible yog ib qho chaw kuaj tshwj xeeb ua los ntawm cov khoom siv graphite. Feem ntau yog siv nyob rau hauv kub smelting, tshuaj lom neeg cov tshuaj tiv thaiv, cov ntaub ntawv kho cua sov thiab lwm yam kev sim.
Graphite crucible muaj qhov kub thiab txias tsis kam thiab tshuaj lom neeg ruaj khov, tuaj yeem tiv taus corrosion ntawm cov khoom kub kub molten, thiab muaj thermal conductivity thiab mechanical zog, haum rau ntau yam kev siv hauv chav kuaj. Graphite crucible muaj ntau yam zoo thiab yog ib qho ntawm cov cuab yeej siv hauv chav kuaj.
Ua ntej ntawm tag nrho cov, cov khoom siv graphite muaj siab purity thiab tsis muaj impurity cov ntsiab lus, uas muaj peev xwm muab ib tug kuj ntshiab kev sim ib puag ncig thiab tsis txhob cuam tshuam cov impurities ntawm qhov kev sim. Graphite crucible muaj qhov kub thiab txias tsis kam, tuaj yeem ua kom cov qauv ruaj khov ntawm qhov kub tsis muaj deformation, thiab tuaj yeem tiv taus corrosion thiab yaig ntawm cov khoom kub kub molten. Tsis tas li ntawd, cov khoom siv graphite muaj cov thermal conductivity zoo, uas tuaj yeem ua kom sov thiab sib npaug, txhim kho cov tshuaj tiv thaiv thiab kev ua haujlwm zoo. Graphite crucible yog dav siv nyob rau hauv ntau yam ntawm chemistry, metallurgy, ntaub ntawv science thiab lwm yam kev kuaj. Nws tuaj yeem siv rau hauv kev sim kub kub melting kev sim, thermal tsom xam kev sim, combustion sim, catalytic sim thiab lwm yam. Nyob rau tib lub sijhawm, graphite crucible kuj tau siv dav hauv cov khoom siv hlau thiab ceramic smelting thiab kho cua sov txheej txheem, xws li smelting hlau kuaj, sintered ceramic cov ntaub ntawv.
Muaj ntau qhov zoo rau kev siv graphite crucible. Ua ntej, cov khoom tsis zoo adsorption ntawm graphite cov ntaub ntawv tuaj yeem txo cov qauv poob thiab ntsuas qhov yuam kev, thiab txhim kho qhov tseeb ntawm cov ntaub ntawv sim. Qhov thib ob, cov graphite crucible muaj kev tiv thaiv corrosion zoo thiab tuaj yeem tiv taus corrosion ntawm ntau yam acids, alkalis, hnyav thiab lwm yam tshuaj, ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov txheej txheem sim. Tsis tas li ntawd, cov khoom siv graphite muaj lub neej ua haujlwm ntev thiab cov nqi kho mob qis, ua rau nws yog ib qho ntawm cov cuab yeej siv hauv kev sim hauv cov chaw soj nstuam.
Hauv cov ntsiab lus, cov graphite crucible yog ib qho chaw kuaj muaj zog uas tuaj yeem muab qhov chaw sim ruaj khov nyob rau hauv qhov kub thiab txias thiab chemically corrosive ib puag ncig. Nws zoo heev kub tsis kam, tshuaj stability thiab thermal conductivity ua rau nws ua lub luag haujlwm tseem ceeb hauv ntau yam kev sim.
