I-Carbon Bonded Silicon Carbide Crucibles
1. ZiyiniI-Carbon Bonded Silicon Carbide Crucibles?
I-Carbon Bonded Silicon Carbide (SiC) crucibles iziqukathi zomlilo ezenziwe ngenhlanganiselai-silicon carbide ne-carbon. Le nhlanganisela inikeza i-crucible enhle kakhuluukumelana nokushaqeka okushisayo, izinga lokuncibilika okuphezulu, futhiukungabi namakhemikhali, okwenza kube ilungele izicelo ezihlukahlukene zezimboni nezaselabhorethri.
Lawa ma-crucibles angakwazi ukumelana namazinga okushisa angaphezulu2000°C, okuqinisekisa ukuthi zisebenza kahle kakhulu ezinqubweni ezibandakanya izinto ezisezingeni lokushisa eliphezulu noma ama-reagents amakhemikhali. Ezimbonini ezifanaukubunjwa kwensimbi, ukukhiqizwa kwe-semiconductor, kanye nocwaningo lwezinto zokwakha, lezi zinhlamvu zibalulekile ekuzuzeni imiphumela yekhwalithi ephezulu.
2. Izici Eziyinhloko Zezikhiqizo Ze-Carbon Bonded Silicon Carbide
- High Thermal Conductivity: I-Silicon carbide ivumela ukudluliswa kokushisa okusheshayo nokufana okufanayo, ukunciphisa isikhathi sokuncibilika nokusetshenziswa kwamandla.
- Ukuqina: I-carbon bonding inikeza amandla engeziwe, okwenza lezi ziphambano zimelane nokuqhekeka nokugqoka ngesikhathi sokushisa nokupholisa imijikelezo.
- Ukungangeni Kwamakhemikhali: Lezi zinhlayiya zimelana nokusabela ngezinsimbi ezincibilikisiwe, ziqinisekisa ubumsulwa enqubweni yokuncibilika.
- Ukumelana ne-Oxidation: Ama-SiC crucibles ajwayelene ne-oxidation ngisho namazinga okushisa aphezulu, anweba isikhathi sawo sokuphila.
3. Ukufakwa kwe-Carbon Bonded Silicon Carbide Crucibles
a) Ukuncibilika kwensimbi:
I-Carbon bonded SiC crucibles isetshenziswa kakhulu ekuncibilikiseni izinsimbi ezifanaithusi, i-aluminium, igolide, nesiliva. Ikhono lazo lokumelana namazinga okushisa aphezulu kanye nokumelana nokuhlangana kwamakhemikhali nezinsimbi ezincibilikisiwe kuzenza zibe yintandokazi ezimbonini eziyisisekelo nezimboni zensimbi. Umphumela?Izikhathi zokuncibilika ngokushesha, ukonga amandla okungcono, nokuhlanzeka okuphezulu komkhiqizo wokugcina wensimbi.
b) Ukukhiqiza I-semiconductor:
Kuzinqubo ze-semiconductor, njengeukufakwa komhwamuko wamakhemikhalifuthiukukhula kwekristalu, I-SiC crucibles ibalulekile ekuphatheni izinga lokushisa eliphezulu elidingekayo ekudaleni ama-wafers nezinye izingxenye. Yaboukuzinza okushisayoiqinisekisa ukuthi i-crucible ibambelela ngaphansi kokushisa okukhulu, futhi yaboukumelana kwamakhemikhaliiqinisekisa ukuthi akukho ukungcoliswa kwenqubo yokukhiqiza i-semiconductor ebucayi kakhulu.
c) Ucwaningo Nentuthuko:
Kusayensi yezinto zokwakha, lapho ukuhlolwa kwezinga lokushisa eliphezulu kuvamile,I-carbon bonded SiC crucibleszilungele izinqubo ezifanai-ceramic synthesis, ukuthuthukiswa kwezinto ezihlanganisiwe, futhiukukhiqizwa kwe-alloy. Lawa ma-crucibles agcina ukwakheka kwawo futhi amelana nokuwohloka, aqinisekisa imiphumela ethembekile futhi ephindaphindwayo.
4. Isetshenziswa Kanjani I-Carbon Bonded Silicon Carbide Crucibles ukuze uthole Imiphumela Engcono Kakhulu
- Ukushisa kuqala: Ngaphambi kokusetshenziswa kokuqala, shisa kuqala i-crucible at200-300°Camahora angu-2-3 ukuqeda umswakama futhi uvimbele ukushaqeka okushisayo.
- Layisha Amandla: Ungalokothi weqe umthamo we-crucible ukuze uqinisekise ukugeleza komoya okulungile nokushisisa okufanayo.
- Ukushisisa okulawulwayo: Uma ubeka i-crucible esithandweni somlilo, phakamisa kancane izinga lokushisa ukuze ugweme ukuqhekeka okubangelwa ukushintsha okusheshayo kwezinga lokushisa.
Ukulandela lezi zinyathelo kungandisa isikhathi sempilo ye-crucible futhi kuthuthukise ukusebenza kahle kokusebenza.
5. Ubuchwepheshe Bethu Nobuchwepheshe
Enkampanini yethu, sisebenzisaukucindezela okubandayo kwe-isostaticukuqinisekisa ukuminyana okufanayo namandla kuwo wonke ama-crucible. Le ndlela iqinisekisa ukuthi izinsimbi zethu ze-SiC azinasici futhi zingakwazi ukuphatha ngisho nezicelo zezimboni ezidingeka kakhulu. Ukwengeza, esiyingqayizivele yethuanti-oxidation enamathelaithuthukisa ukuqina nokusebenza, yenza iziphambano zethukufika ku-20% okuhlala isikhathi esidekunalezo eziqhudelana naye.
