Fahimtar Bambance-Bambance Tsakanin Clay Graphite Crucibles da Graphite Silicon Carbide Crucibles

Lokacin gudanar da gwaje-gwajen sinadarai masu zafin jiki ko aikace-aikacen masana'antu, zaɓin kayan ƙwanƙwasa yana taka muhimmiyar rawa wajen tabbatar da nasara da amincin tsarin. Nau'o'in crucibles da aka saba amfani da su sunelãka graphite crucibleskumagraphite silicon carbide crucibles. Fahimtar abun da ke tattare da kayan sa, zazzabi mai jujjuyawa, rashin kuzarin sinadarai, da ma'aunin zafi yana da mahimmanci don yanke shawara mai fa'ida lokacin zabar abin da ya dace don takamaiman dakin gwaje-gwaje ko bukatun masana'antu.

sinadarai:
Clay graphite crucible ya ƙunshi graphite, yumbu da wani adadin mai, kuma an san shi da rashin kuzarin sinadarai. A gefe guda kuma, graphite silicon carbide crucible an yi shi ne da siliki carbide foda da wasu abubuwan da ba kasafai ake samun su ba, kuma yana da halaye na juriya mai zafi, kyakkyawan juriya na zafin zafi, da rashin kuzarin sinadarai.

Yanayin juriya na wuta:
Matsakaicin zafin jiki na yumbu graphite crucibles gabaɗaya ya kai kusan 1200 ° C, yayin da graphite silicon carbide crucibles zai iya jure yanayin zafi sama da 1500 ° C. Wannan ya sa graphite silicon carbide crucibles ya fi dacewa da aikace-aikacen da ke buƙatar yanayin zafi a cikin gwaje-gwajen sinadarai da hanyoyin masana'antu.

Kemikal inert:
Dukansu nau'ikan crucibles suna nuna matakin rashin kuzarin sinadarai, sauran barga a mafi yawan acid, alkali, da maganin gishiri da juriya ga lalata. Duk da haka, ɓangaren yumbu a cikin crucibles graphite na yumbu yana sa ya zama sauƙi don ɗaukar abubuwa masu alama da ƙazanta idan aka kwatanta da graphite silicon carbide crucibles.

Ƙarfafa Ƙarfafawa:
Graphite yana da babban ƙarfin wutar lantarki kuma yana iya watsar da zafi da sauri. Duk da haka, saboda sassauƙan tsarin yumbu graphite crucible, baƙar fata suna da wuya su bayyana a samansa kuma suna buƙatar tsaftacewa akai-akai. Sabanin haka, graphite silicon carbide crucibles suna da ƙananan ƙarancin zafin jiki kuma ba za su bar tabo a saman ba. Bugu da ƙari, babban taurin su yana hana lalacewa da lalacewa.

Zaba madaidaicin ƙugiya:
Lokacin zabar crucible na sinadarai, takamaiman buƙatu dole ne a yi la'akari da su. Clay graphite crucibles sun dace da gwaje-gwajen sunadarai na gabaɗaya, yayin da graphite silicon carbide crucibles suna da kyau don gwaje-gwajen da ke buƙatar yanayin zafi mai girma da ƙarin yanayi mai buƙata. Yana da mahimmanci a bi ƙa'idodin amfani sosai don guje wa gazawar gwaji saboda aiki mara kyau.

A taƙaice, fahimtar bambance-bambancen da ke tsakanin ƙwanƙwasa faifan lãka da graphite silicon carbide crucibles yana da mahimmanci don zaɓar mafi dacewa crucible don takamaiman dakin gwaje-gwaje ko aikace-aikacen masana'antu. Ta hanyar la'akari da dalilai irin su zafin jiki na refractory, sinadarai inertness da thermal conductivity, masu bincike da masana'antu masana'antu za su iya yanke shawarar da aka sani don tabbatar da nasara da amincin gwaje-gwaje da matakai.
