I-Sapphire (Al2O3)

I-Sapphire (Al2O3)

Sapphire (Al₂O₃)

Sapphire (Al₂O₃) iyi-crystal aluminium oxide eyodwa (Al₂O₃) enobulukhuni be-Mohs obungu-9, ingenye yezinto ezinzima kakhulu. Lokhu kuqina okwedlulele kwesafire kwenza kube nzima ukupholisha usebenzisa amasu ajwayelekile. Ukuqedwa kwekhwalithi ephezulu ye-optical kusafire akwenzeki ngaso sonke isikhathi. Njengoba i-Sapphire iqinile kakhulu futhi inamandla amahle okusebenza, ihlale isetshenziswa njengefasitela impahla lapho kudingeka ukumelana nokuklwebheka. Iphuzu layo eliphakeme lokuncibilika, ukuqhutshwa kahle kwe-thermal kanye nokwanda okuphansi kokushisa kunikeza ukusebenza okuhle kakhulu ezindaweni zokushisa okuphezulu. I-Sapphire ayisebenzi ngamakhemikhali futhi ayincibiliki emanzini, ama-asidi avamile, nama-alkali emazingeni okushisa afika ku-1,000 °C. Isetshenziswa kakhulu ezinhlelweni ze-laser ye-IR, i-spectroscopy, kanye nemishini yemvelo eqinile.

Igrafu

Igrafu engakwesokudla ijika lokudlulisela elingu-10 mm ubukhulu, i-substrate yesafire engagcotshiwe

Amathiphu: I-Sapphire i-birefringent kancane, amafasitela e-IR enhloso ejwayelekile ngokuvamile asikwa ngendlela engahleliwe ukusuka kukristalu, nokho umumo ukhethwa wezinhlelo zokusebenza ezithile lapho i-birefringence kuyinkinga. Ngokuvamile lokhu kuhambisana ne-optic axis kuma-degree angu-90 ukuya endizeni engaphezulu futhi kwaziwa ngokuthi "zero degree". Isafire ye-synthetic optical ayinawo umbala.

Ukuze uthole imininingwane eningilizayo eningiliziwe, sicela ubuke ikhathalogi yethu yokubona ukuze ubone ukukhetha kwethu okuphelele kwe-optics eyenziwe ngesafire.
