I-Pyrolytic Graphite Coated Crucible
I-Semixlab Pyrolytic Graphite Coated Crucible ingumkhumbi okhethekile owenzelwe izinga lokushisa eliphezulu, i-vacuum ephezulu kanye nezindawo ezigqwalile, osetshenziswa kakhulu ekuhwamukeni kwe-electron beam, i-vacuum coating, ukukhiqizwa kwe-semiconductor neminye imikhakha. Sibheke phambili embuzweni wakho oqhubekayo.
Incazelo
I-PG Coated Carbon Crucible iwumkhiqizo ogaywe ngokukhethekile. Ivamise ukusetshenziselwa ukuhwamuka, ukuncibilika kanye nokufakwa kwezinto emazingeni okushisa aphezulu nasezindaweni ezingenalutho, futhi idlala indima ebalulekile ezinqubweni zokuhwamuka kwevacuum ikakhulukazi. Idizayini eyinhloko iwukusebenzisa izici ezibonakalayo ezinhle kakhulu ze-Pyrolytic Graphite ukumboza udonga lwangaphakathi noma yonke indawo ye-crucible, ngaleyo ndlela kuthuthukiswe ukumelana nezinga lokushisa okuphezulu kwe-crucible, ukungabi namandla kwamakhemikhali kanye ne-thermal homogeneity.
Izici Zesakhiwo:
I-Matrix Material kanye Nesakhiwo Sokumboza:
I-Susceptor Material: I-graphite crucibles yethu yenziwe ngezinto ze-graphite njenge-substrate yokuqinisekisa amandla omshini kanye nokumelana nokushisa.
I-Pyrolytic Carbon (PyC) Coating: Ungqimba lwe-high-purity, i-crystalline pyrolytic graphite ifakwe ngokufanayo ngaphakathi noma ngaphandle kwe-crucible ngokusebenzisa inqubo ye-Chemical Vapor Deposition (CVD). Ugqinsi lwe-coating luyi-30 µm ngokuzenzakalelayo. I-coating ine-layer futhi ine-anisotropic kakhulu phakathi kwezingqimba ezibheke ekukhuleni kwekristalu. Ukuhlanzeka kwe-coating kudlula i-99.999% futhi okuqukethwe kokungcola kungaphansi kuka-10 ppm, okwenza kulunge ngokukhethekile izinqubo ezinezidingo eziqinile zokuhlanzeka. Siphinde sisekele ukujiya okwenziwe ngezifiso ngokwezidingo zakho.
Ukumelana nokuvalwa nokuguguleka komhlabathi:
Izingubo zethu zine-porosity ephansi kakhulu kanye nendawo ebushelelezi (isb. epholishelwe isibuko) ngakho-ke ivikela i-substrate ngokumelene nokusabela kwamakhemikhali phakathi kwento encibilikisiwe nesisekelo se-crucible emazingeni aphezulu okushisa, ngaleyo ndlela andise impilo yesevisi ye-crucible.
Endaweni engenalutho kanye ne-inert, i-pyrolytic graphite ibonisa ukumelana nokuguguleka okuhle kakhulu, iqinisekisa ukuthi impahla ngeke ingcoliswe ukusabela kwamakhemikhali ngomkhumbi noma ngokungena endaweni yokushisa ephezulu.
I-PG Coated Carbon Crucible Packaging
I-Pyrolytic Graphite Coated Crucible yethu izopakishwa ngokuhlanganyela namakhreyithi enziwe ngokhuni asondelene kakhulu nenani elikhulu legwebu, futhi isingathwe ngokucophelela ngesikhathi sokugcinwa nokuthuthwa ukuze kugcinwe izinga lokuqala lemikhiqizo yethu. Sibheke phambili embuzweni wakho oqhubekayo!

Izicelo
Indima ethile ekuhwameni kwevacuum:
1. Ukulawula ukushisisa nokuhwamuka okufanayo:
I-graphite ye-pyrolytic ehlanganiswe odongeni lwangaphakathi lwe-crucible inganikeza ukuqhutshwa okuhle kokushisa ukuze kuqinisekiswe ukusatshalaliswa kwezinga lokushisa okufanayo ngesikhathi senqubo yokushisa, ukuze izinto ezizokhishwa zihwamuke ngokuzinzile nangokufanayo ku-vacuum.
2. Vimbela ukusabela kwamakhemikhali kanye nokungcola:
I-high conductivity eshisayo ye-pyrolytic graphite iqinisekisa ukuthi impahla ehwamukile (isb i-aluminium) iyashiswa ngokufanayo, okuthuthukisa ikhwalithi yokumboza; Okwamanje, ukungabi namakhemikhali kwamakhemikhali e-PG kuvimbela insimbi encibilikisiwe ekuphenduleni nge-crucible, egwema ukukhiqizwa kokungcola kanye nokungcoliswa okungenzeka.
3. Thuthukisa ukuzinza kwenqubo nokuphindaphinda:
Ngenxa yokumelana kwayo nezinga lokushisa eliphakeme kakhulu kanye nezici eziphansi zokunwetshwa kokushisa, ukusetshenziswa kwe-PG Coated Carbon Crucible kunganciphisa kakhulu ukushintshashintsha kwenqubo okubangelwa ukushintshashintsha kwezinga lokushisa noma ukushisa okweqile kwendawo, ngaleyo ndlela kuthuthukise ukungaguquguquki komkhiqizo. Isibonelo, ekuhwamukeni kwe-electron beam, izinsimbi ze-Graphite ezine-PG coating zingamelana nokuqhuma kwemishayo yama-electron enamandla amakhulu, zigcine ukuqina kwesakhiwo nokuvimbela okokusebenza ekushibilikeni nasekuphumeni ekulawuleni.
4. Nweba impilo yesevisi yezisetshenziswa:
I-porosity ephansi kanye nokumelana nokugqwala okuphezulu kwe-Pyrolytic Graphite enamathela kunciphisa ngempumelelo ukuguguleka kwezinto. Isibonelo, kunqubo ye-vacuum aluminizing, i-Pyrolytic Graphite Crucible ingasetshenziswa ngokuqhubekayo amahora angu-24-52, okunciphisa kakhulu imvamisa yokushintshwa nezindleko zokukhiqiza.
