Isithombe Esifakiwe Sendlela Ye-EFG Sapphire Tube Element Free Galerkin

Incazelo emfushane:

Ishubhu le-sapphire le-EFG, elikhiqizwe inqubo ye-Edge-Defined Film-Fed Growth (EFG), liwumkhiqizo we-single-crystal aluminium oxide (Al₂O₃) owaziwa ngokuqina kwawo okuvelele, ubumsulwa, kanye nokusebenza kahle kokukhanya. Indlela ye-EFG ivumela amashubhu e-sapphire ukuthi akhuliswe ngqo ku-geometry yamashubhu, akhiqize izindawo ezibushelelezi kanye nobukhulu bodonga obuhambisanayo ngaphandle kokucutshungulwa kabanzi ngemuva kokucubungula. Lawa mashubhu e-sapphire abonisa ukuzinza okumangalisayo ezindaweni ezishisa kakhulu, ezinomfutho ophezulu, kanye nezingcolisayo, okwenza abe yinto ebalulekile ezisetshenziswayo zezimboni nezesayensi ezithuthukile.

Ukubuka Konke Komkhiqizo

IIshubhu le-sapphire le-EFG, ekhiqizwe yi-Ukukhula Kwefilimu Echazwe Ngokuphelele (i-EFG)ubuchwepheshe, umkhiqizo we-single-crystal aluminium oxide (Al₂O₃) owaziwa ngokuqina kwawo okumangalisayo, ubumsulwa, kanye nokusebenza kwawo okubonakalayo. Indlela ye-EFG ivumela amashubhu e-sapphire ukuthiikhule ngqo ku-geometry yeshubhu, okudala izindawo ezibushelelezi kanye nobukhulu bodonga obuhambisanayo ngaphandle kokucutshungulwa kabanzi ngemuva kokucubungula. Lawa mashubhu e-safire abonisa ukuzinza okumangalisayo kuizindawo ezinokushisa okuphezulu, umfutho ophezulu, kanye nezindawo ezigqwalisayo, okwenza zibe usizo kakhulu ezisetshenziswayo zezimboni nezesayensi ezithuthukile.

Ubuchwepheshe Bokukhula kwe-EFG

Inqubo yokukhula kwe-EFG isebenzisaithuluzi lokudaya noma lokubumbaokuchaza imingcele yangaphandle nengaphakathi yekristalu njengoba izinto zesafire ezincibilikisiwe zidonswa phezulu. Ngokulawulwa okunembile kwefilimu yokuncibilikisa edla ama-capillary, ikristalu yesafire iqina ibe yi-aisilinda esingenalutho esingenalutho.

Le ndlela iqinisekisa ukuthi umkhiqizo wokugcina ugcinaubukhulu obufunwayo kanye nokuqondiswa kwekristalografi, kunciphisa isidingo somshini wesibili. Ngenxa yokuthi i-sapphire yakhiwe ngqo ngesimo sayo sokusebenza, inqubo ye-EFG inikezaukuphindaphindeka okuhle kakhulu, isivuno esikhulu, kanye nokukhula okungabizi kakhuluukukhiqizwa ngobuningi obukhulu.

Izici Zokusebenza

Ukudluliselwa Okubanzi Kokukhanya:Idlulisela ukukhanya kusuka ku-ultraviolet (190 nm) kuya kububanzi be-infrared (5 µm), okulungele ukusetshenziswa kokubona, ukuhlaziya, kanye nokuzwa.
Amandla Aphezulu Esakhiwo:Isakhiwo se-monocrystalline sinikeza ukumelana okuphezulu kokucindezeleka komshini, ukushaqeka kokushisa, kanye nokuguqulwa.
Ukuzinza Okumangalisayo Kokushisa:Ingasebenza ngokuqhubekayo ku-amazinga okushisa angaphezu kuka-1700°Cngaphandle kokuthambisa, ukuqhekeka, noma ukuwohloka kwamakhemikhali.
Ukumelana Kwamakhemikhali Ne-Plasma:Ama-asidi aqinile, ama-alkali, namagesi asabelayo angasebenzi kahle, afanelekela izindawo ze-semiconductor kanye neze-laboratory.
Ikhwalithi Yomphezulu Obushelelezi:Ubuso be-EFG obukhulile sebuvele bulungile futhi bufana, okuvumela ukupholisha noma ukumboza okubonakalayo uma kudingeka.
Isikhathi Eside Sokuphila kanye Nokunakekelwa Okuphansi:Ngenxa yokumelana nokuguguleka kwe-sapphire, amashubhu e-EFG ahlala isikhathi eside ngisho noma esetshenziswa kakhulu.
