Yiziphi izinhlelo zokusebenza ze-graphite crucible?

Iyini i-graphite crucible?

I-graphite crucibleyingxenye ebalulekile yezimboni, esetshenziswa kabanzi emikhakheni ehlukahlukene yezimboni, njenge-metallurgy, casting, imishini, chemistry, semiconductor , njll. Kuyinto ekahle yokudlulisa ukushisa kanye nomqhubi, ongakwazi ukuqhuba ngokuphumelelayo ukushisa nogesi ekukhiqizeni futhi kungakwazi ukwamukela inani elikhulu lezingxenye. Ekwenziweni kwe-semiconductor, i-graphite crucible idlala indima ebalulekile futhi ingenye yemishini ebaluleke kakhulu ekukhiqizeni ama-semiconductor.

Yiziphi izinhlobo nezici ze-graphite crucibles?

Kunezinhlobo eziningi ze-graphite crucibles, futhi kunezingqimba ze-graphite ezifanele izikhathi ezihlukahlukene, njengezintambo eziyindilinga, izikwele zesikwele, izinsimbi ezihlanganisiwe, njll. Izinhlobo ezahlukene ze-graphite crucibles zinezici ezihlukene, kodwa zonke zinokudlulisa ukushisa okuhle kakhulu kanye ne-conductivity kagesi, engathuthukisa ngokuphumelelayo ukusebenza kahle kwemishini.

I-graphite crucibles nayo ingahlukaniswa ngokuningiliziwe ngokuya ngezindawo ezihlukene zokusetshenziswa:
1. I-crucible evamile: ilungele ukuncibilika, ukushisa nokugcinwa kokushisa kwezinsimbi ezijwayelekile kanye nama-alloys.
2. I-crucible yokushisa ephezulu: ilungele ukuncibilika izinsimbi eziphikisayo nama-alloys emazingeni okushisa aphezulu, njenge-tungsten, i-molybdenum, i-tantalum, njll.
3. I-Synthesis crucible: isetshenziselwa ukuhlanganiswa nokulungiselela izinto ezihlanzekile, njengezinto ze-semiconductor, izinto zobumba, njll.
4. I-vacuum crucible: ilungele ukushisa nokuncibilika endaweni ye-vacuum, ikakhulukazi esetshenziselwa ukulungiswa kwezinto ezikhethekile kanye nokuncibilika kwezinsimbi ezihlanzekile.

Impahla yokukhiqiza ye-graphite crucible inokumelana okuhle nokushisa okuphezulu kanye nokuzinza kwamakhemikhali. Ingasetshenziswa ekushiseni okuphezulu ngaphandle kokuguqulwa noma ukulimala ngenxa yokushisa okuphezulu. Ngesikhathi esifanayo, i-graphite crucible nayo inokumelana nokugqwala okuhle kakhulu futhi ingamelana ngokuphumelelayo nokuguguleka kwezinto ezihlukahlukene zamakhemikhali, ngaleyo ndlela iqinisekise ikhwalithi yokukhiqiza yamadivayisi we-semiconductor.

Yiziphi izinhlelo zokusebenza eziyinhloko zama-graphite crucible ku-semiconductor?

Enqubweni yokukhiqiza i-semiconductor,ama-graphite crucibleszisetshenziselwa kakhulu ukuthwala nokuvikela izingxenye ze-semiconductor, futhi zingadlulisela ngempumelelo ukushisa namanje. Ngokusebenzisa isibambo kanye nabakaki abathathu abalungisiwe phansi kwe-graphite crucible, inani elikhulu lezingxenye ze-semiconductor lingafakwa ku-graphite crucible ukuze zithintane kahle ne-graphite crucible, ngaleyo ndlela idlulise ngempumelelo ukushisa namanje.

Ngaphezu kwalokho, i-graphite crucible nayo ingasetshenziswa njenge-conductor ekahle eshisayo nekagesi. Ngenxa ye-conductivity ephezulu ye-thermal kanye ne-conductivity kagesi, i-graphite crucible ingakwazi ukuqhuba ukushisa kanye namanje kusukela ngaphandle kwemishini kuya ezingxenyeni ze-semiconductor ngaphakathi kwe-graphite crucible, ngaleyo ndlela ukushisa ngokuphumelelayo izingxenye ze-semiconductor nokulawula okwamanje.

Ngaphezu kwalokho, i-graphite crucible ingasebenza futhi njengokushisa okuhle kanye nomqhubi kagesi, ongakwazi ukufaka inani elikhulu lezingxenye ze-semiconductor, okuvumela ukuthi imishini icubungule izingxenye eziningi ngesikhathi esisodwa, ngaleyo ndlela ithuthukise ukusebenza kahle kokucubungula kwemishini.

Yiziphi izinhlelo zokusebenza ze-graphite crucible embonini?

Ukuzinza okuphezulu kwezinga lokushisa kanye nokuzinza kwamakhemikhali e-graphite crucible kwenza ukuba ikwazi ukumelana nokuncibilika kwensimbi emazingeni okushisa aphezulu, iqinisekisa ikhwalithi nokuzinza kwezinto ezincibilikisiwe. Ngakho-ke, ingasetshenziswa ukulungisa nokuncibilikisa izinto ezihlukahlukene zensimbi, njengethusi, i-aluminium, i-zinc, njll. Ngaphezu kwalokho, i-graphite crucible ingasetshenziswa futhi ukulungisa nokuncibilikisa izinto ze-alloy.

Ngaphezu kwalokho, ama-graphite crucibles nawo anokumelana nokugqwala okuhle. I-graphite inokumelana nokugqwala okuqinile kumakhemikhali amaningi futhi ingamelana nokuguguleka kwezinto ezonakalisayo njengama-asidi, ama-alkali, nezinyibilikisi. Ngakho-ke, ama-graphite crucibles avame ukusetshenziselwa ukugcina, ukuphatha, nokuhlaziya izinto ezonakalisayo. Isibonelo, embonini yamakhemikhali, ama-graphite crucibles angasetshenziselwa ukuqoqa amasampula, izinto ezincibilikayo, nokugcina ama-acidic reagent. Ku-organic synthesis, ama-graphite crucibles angasetshenziswa ekwelapheni ama-solvents asabelayo kanye nama-catalysts, kanye nenqubo ye-crystallization kanye nokomisa kwezinto eziphilayo.

Ukufingqa

Ngaphezu kokusebenza kwayo ekukhiqizeni i-semiconductor, izinsimbi ze-graphite nazo zingadlala indima ebalulekile ku-metallurgy, casting, imishini, chemistry kanye neminye imikhakha. Isibonelo, embonini ye-metallurgical, ama-graphite crucibles angasetshenziswa ukuncibilikisa nokucwenga izinto zensimbi; embonini yokuphonsa, ama-graphite crucibles angasetshenziswa ukuncibilikisa izinto zensimbi futhi enze imikhiqizo ehlukahlukene yensimbi; embonini yamakhemikhali, ama-graphite crucibles angasetshenziswa njengama-reactors noma iziqukathi zokusabela kwamakhemikhali. Ngakho-ke, ukubaluleka kwe-graphite crucibles akubonakali kuphela emikhakheni yesicelo sayo, kodwa futhi indima ebalulekile ekukhiqizeni izimboni. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, amathemba okusetshenziswa kwe-graphite crucibles azoba banzi.
