Umehluko phakathi kwe-graphite silicon carbide ne-clay graphite crucibles

I-graphite silicon carbide crucibleskanye nezinsimbi zobumba ze-graphite yimikhumbi emibili evamile yaselabhorethri enomehluko othile obalulekile ezintweni, izakhiwo, kanye nezicelo.

Okubalulekile:

I-graphite silicon carbide crucible: Yenziwe nge-graphite silicon carbide material, inokuqina kwezinga lokushisa eliphezulu, ukumelana nokugqwala kanye nokuhamba kahle kwe-thermal.
I-Clay graphite crucible: ngokuvamile eyenziwe ngengxube yobumba ne-graphite, enokuqukethwe okuphansi kwe-graphite, ikakhulukazi isebenzisa ubumba njengento eyisisekelo, futhi i-graphite yengezwa ikakhulukazi ukuthuthukisa ukumelana kwayo nokushisa okuphezulu.
Ukumelana nezinga lokushisa:

I-graphite silicon carbide crucible: Ingakwazi ukumelana namazinga okushisa aphakeme kakhulu futhi ngokuvamile ingasetshenziswa ezingeni lokushisa elingu-1500°C kuya ku-2000°C noma ngisho nangaphezulu.
I-Clay graphite crucible: Ukumelana nezinga lokushisa kuphansi, futhi izinga lokushisa elivamile elisetshenziswayo lingu-800°C kuya ku-1000°C. Ukweqa leli banga lokushisa kungabangela kalula umonakalo noma ukuguqulwa kwe-crucible.
Ukumelana nokugqwala:

I-graphite silicon carbide crucible: Inokumelana nokugqwala okuphezulu futhi ingamelana nokuguguleka kwamakhemikhali njengama-acids nama-alkali.
I-Clay Graphite Crucible: Ngenxa yobumba bayo obuphezulu uma kuqhathaniswa ne-graphite silicon carbide, ingase ingamelani namakhemikhali athile agqwala kakhulu.
I-Thermal Conductivity:

I-graphite silicon carbide crucible: Inokusebenza kahle kwe-thermal futhi ingadlulisela ukushisa kusampula ngokushesha nangokulinganayo.
I-Clay graphite crucible: Ukuhamba kwayo okushisayo kungase kube kubi kakhulu kune-graphite silicon carbide crucible.
Inani kanye nesicelo:

I-graphite silicon carbide crucible: Ivamise ukubiza kakhulu, kodwa ifanele ukuhlolwa nezinhlelo zokusebenza ezidinga amazinga okushisa aphezulu nokumelana nokugqwala.
I-clay graphite crucible: Intengo iphansi uma kuqhathaniswa, ifanele ukusetshenziswa kwelabhorethri evamile, izikhathi lapho izidingo zokushisa zingekho phezulu, noma lapho izidingo zokumelana nokugqwala zingeqinile kakhulu.
Ngamafuphi, i-graphite silicon carbide crucibles kanye ne-clay graphite crucibles inomehluko omkhulu ezintweni ezibonakalayo, ukumelana nezinga lokushisa, ukumelana nokugqwala, ukuqhutshwa kwe-thermal, njll. Ukukhetha ukuthi yiluphi uhlobo lwe-crucible okufanele lusetshenziswe kufanele lusekelwe ezidingweni ezithile zokuhlola kanye nezidingo. Ungathintana nathi futhi sizokunikeza ngamasevisi ochwepheshe.
