Gaosi Mea | Faʻaaogaina e faʻaaoga ai Czochralski (CZ) ma Kyropoulos (KY) metotia mo le saʻo ma le faʻamaoni |
Talosaga | E masani ona faʻaaogaina i le gaosiga o le semiconductor, ogaumu vevela maualuga, optics, aerospace, ma fale kemisi. |
XINKEHUI faagaau safaira meatotino tube
Fa'aaogāga o Mea
Sapphire tubes o loʻo faʻaaogaina lautele i pisinisi maualuga e pei o le semiconductor processing, aerospace, optics, ma le inisinia kemisi. O lo latou gafatia e tetee atu i le vevela tele (e oo atu i le 1,600°C), faʻatasi ai ma le faʻaogaina o vailaʻau faʻapitoa i acids ma alkalis, e lelei ai mo ogaumu vevela maualuga ma siosiomaga pala. E le gata i lea, o lo latou manino maualuga i luga o le UV i le IR wavelengths e taua ai i latou i masini mata. O le malosi faʻainisinia maualuga o le paipa sapphire ma le faʻaogaina o le vevela e taua tele mo faʻaoga e manaʻomia ai le tumau ma le faʻafefe o le vevela, e pei o le eletise ma le eletise.
Aotelega Aotelega
O le sapphire tube, na faia mai le 99.999% mama Al₂O₃ tasi tioata safaira, o se mea tulaga ese ua fuafuaina mo le faaaogaina i alamanuia maualuga-faatinoga e pei o semiconductors, aerospace, optics, ma inisinia kemisi. Faatasi ai ma le maaa o le 9 i luga o le fua Mohs, e ofoina atu le sili atu o le malosi ma le malosi faʻainisinia. E mafai ona galue i totonu o siosiomaga ogaoga ma le vevela e oʻo atu i le 1,600 ° C, faʻapitoa mo ogaumu vevela maualuga ma faʻalavelave faʻaleagaina ona o lona faʻamaʻi sili ona lelei.
E le gata i lea, o le sapphire tube's thermal conductivity o le 46 W/m·K fa'amautinoaina le fa'amama lelei o le vevela, ae o lona fa'amalamalamaga maualuga i luga o le UV i le IR wavelengths e lagolagoina ai fa'aoga mata'utia. Faʻatasi ma ona mea sili ona lelei dielectric, o lenei oloa o se vaifofo malosi mo mea faʻaeletonika, faiga eletise, ma optics. Faatasi ai ma le maualuga o le tumau, mautu, ma le faʻatinoga, o sapphire tubes e tuʻuina atu le faʻatuatuaina i nisi o siosiomaga faʻapisinisi ma tekinolosi sili ona faigata.
