Umehluko Phakathi Kweziphambano Ze-Silicon Carbide kanye Neziphambano Ze-Graphite

I-silicon carbide crucibleskanye nama-graphite crucibles ngokuvamile asetshenziselwa iziqukathi zokushisa okuphezulu kuma-laboratories kanye nezilungiselelo zezimboni. Abonisa umehluko omkhulu ezinhlotsheni zezinto ezibonakalayo, ubude bempilo, amanani, ububanzi obusebenzayo, nokusebenza. Nakhu ukuqhathanisa okuningiliziwe ukusiza ekukhetheni i-crucible efaneleke kakhulu ngezidingo ezithile:

1. Izinhlobo zezinto:

• I-Silicon Carbide Crucibles: Imvamisa eyenziwe ngezinto ze-silicon carbide, lezi zinsimbi zinikeza ukumelana okuhle kakhulu kwezinga lokushisa eliphezulu nokumelana nokugqwala. Zifaneleka kahle izinqubo ezifana nokucwilisa, ukwelashwa kokushisa, nokukhula kwekristalu yezinsimbi nezitsha zobumba.
• I-Graphite Crucibles: Iklanywe ngokuyinhloko kusukela ku-graphite ye-flake yemvelo, eyaziwa nangokuthi i-graphite clay crucibles, ithola ukusetshenziswa ekwelapheni ukushisa nasekukhuleni kwekristalu yakho kokubili okusansimbi nokungeyona insimbi.

2. Ubude bempilo:

• I-Graphite Crucibles: Ngokuphathelene ne-silicon carbide crucibles, izinsimbi ze-graphite zinesikhathi eside sokuphila, ngokuvamile sisukela kokuphindwe kathathu kuya kahlanu kunezinsimbi ze-silicon carbide crucibles.

3. Amanani:

• I-Silicon Carbide Crucibles: Ngenxa yezinqubo zokukhiqiza kanye nezindleko zempahla, izinsimbi ze-silicon carbide ngokuvamile zinenani eliphakeme kakhulu uma kuqhathaniswa ne-graphite crucibles. Nokho, kwezinye izinhlelo zokusebenza, ukusebenza kwazo okuphezulu kungase kuthethelele umehluko wezindleko.

4. Ububanzi obusebenzayo:

• I-Silicon Carbide Crucibles: Ngaphezu kokufaneleka ukucubungula izinsimbi nama-ceramics, ama-silicon carbide crucibles nawo ayasebenza emkhakheni we-electronics kanye ne-optoelectronics.
• I-Graphite Crucibles: Ifanele uhla olubanzi lwezinto zensimbi nezingezona ezensimbi ekwelapheni ukushisa nezinqubo zokukhula kwekristalu.

5. Umehluko Wokusebenza:

• I-Graphite Crucibles: Ngokuminyana okungaba ngu-1.3 kg/cm², umehluko wezinga lokushisa wangaphakathi nangaphandle ocishe ube ngamadigri angu-35, kanye nokumelana okuphansi kwe-asidi nokugqwala kwe-alkali, ama-graphite crucibles angase angahlinzeki ukonga amandla okuqhathaniswa ne-silicon carbide crucibles.
• I-Silicon Carbide Crucibles: Ngobuningi obusuka ku-1.7 ukuya ku-26 kg/mm², umehluko wezinga lokushisa wangaphakathi nangaphandle ongu-2-5 degrees, kanye nokumelana kahle nokugqwala kwe-asidi nokugqwala kwe-alkali, ama-silicon carbide crucibles anikeza ukonga amandla okungaba ngu-50%.

Isiphetho:

Lapho bekhetha phakathi kwe-silicon carbide ne-graphite crucibles, abacwaningi kufanele bacabangele izidingo zokuhlola, izithiyo zesabelomali, kanye nokusebenza okufunayo. I-silicon carbide crucibles ihamba phambili endaweni eshisa kakhulu futhi ebolayo, kuyilapho ama-graphite crucibles enikeza izinzuzo ngokuya ngezindleko eziphansi nokusebenza okubanzi. Ngokuqonda lo mehluko, abacwaningi bangenza izinqumo ezinolwazi ukuze baqinisekise imiphumela emihle ekuhloleni kwabo.
