Iwindi leSapphire Ngesithando Sokushisa Esiphezulu
Ngesikhathi sokusetshenziswa kwesithando somlilo sezimboni kanye namakamelo e-vacuum, iwindi lembobo yokubuka lizobhekana nokucindezela okukhulu kakhulu kanye nezinga lokushisa eliphezulu lokusebenza.Ukuze kuqinisekiswe ukuphepha kwabahloli, iwindi lembobo yokubuka kufanele liqiniswe, lithembeke, limelane nezinga lokushisa eliphezulu, liphinde libe nezinto ezinhle kakhulu zokubona.Isafire yokwenziwa iyinto efanelekile njengefasitela lokubuka.
I-Sapphire inenzuzo yamandla ayo okucindezela: ingakwazi ukumelana nokucindezela ngaphambi kokugqashuka.I-Sapphire inamandla okucindezela acishe abe ngu-2 GPa.Ngokuphambene, insimbi inamandla okucindezela angu-250 MPa (cishe izikhathi eziyisi-8 ngaphansi kwesafire) futhi ingilazi ye-gorilla (™) inamandla okucindezela angu-900 MPa (ngaphansi kwengxenye yesafire).Isafire yona inamakhemikhali amahle kakhulu futhi ayisebenzi cishe kuwo wonke amakhemikhali, okuyenza ifaneleke lapho kukhona khona izinto ezigqwalayo.Ine-conductivity ephansi kakhulu ye-thermal, i-25 W m'(-1) K^(-1), kanye ne-coefficient ephansi kakhulu yokwandisa ukushisa kwe-5.8 × 10 ^ 6 / C: akukho ukuguqulwa noma ukunwetshwa kwezimo ezishisayo phezulu noma phezulu. amazinga okushisa.Noma ngabe imuphi umklamo wakho, ungaqinisekisa ukuthi inosayizi ofanayo nokubekezelela kumamitha ayi-100 ngaphansi kolwandle noma ku-40K ku-orbit.
Sisebenzise lezi zici zamandla kanye namafasitela amelana nokuklwebheka ezinhlelweni zamakhasimende, okuhlanganisa namakamelo evacuum kanye neziko lokushisa eliphezulu.
Iwindi lesafire lesithando somlilo linokudlulisa okuhle kakhulu ku-300nm kuya ku-5500nm ububanzi (okumboza i-ultraviolet, izindawo ezibonakalayo ne-infrared) kanye neziqongo zamazinga okudlulisela cishe ama-90% ku-300 nm kuya ku-500 nm wavelengths.I-Sapphire iyi-double refractive material, ngakho-ke izici zayo eziningi zokubona zizoncika ekuqondeni kwekristalu.Ku-axis yayo evamile, inkomba yayo ye-refractive isukela ku-1.796 ku-350nm kuya ku-1.761 ku-750nm, futhi ngisho noma izinga lokushisa lishintsha kakhulu, lishintsha kancane kakhulu.Ngenxa yokudlulisa ukukhanya okuhle kanye nobubanzi be-wavelength ebanzi, sivame ukusebenzisa iwindi lesafire emiklamo yelensi ye-infrared eziko lapho izibuko ezivame kakhulu zingafanelekile.
Nali ifomula Yokubalwa Kokuzizwisa yobukhulu bewindi lembobo yokubuka yesafire:
Th=√( 1.1 x P x r² x SF/MR)
kuphi:
Th=Ubukhulu bewindi(mm)
P = Ingcindezi yokusebenzisa idizayini (PSI),
r = Irediyasi engasekelwe (mm),
SF = Isici sokuphepha (4 kuya ku-6) (uhla oluphakanyisiwe, lungasebenzisa ezinye izici),
MR = I-Modulus of rupture (PSI).I-Sapphire njenge-65000PSI
Isibonelo, iwindi lesafire elinobubanzi obungu-100 mm kanye nerediyasi engasekelwe engu-45 mm esetshenziswa endaweni enomehluko wokucindezela we-atmosphere engu-5 kufanele ibe nogqinsi luka-~3.5mm (isici sokuphepha esingu-5).
