ISapphire (Al₂O₃)

ISapphire (Al₂O₃) yikristale enye yealuminiyam oxide (Al₂O₃) ngobunzima be-Mohs be-9, yenye yezona zinto zinzima. Obu bunzima bugqithileyo besafire kwenza kube nzima ukupolisha usebenzisa iindlela eziqhelekileyo. Umgangatho ophezulu we-optical finishes kwisafire ayisoloko inokwenzeka. Ekubeni i-Sapphire yomelele kakhulu kwaye inamandla omatshini, isoloko isetyenziswa njengezinto zefestile apho ukuxhatshazwa kwe-scratch kuyadingeka. Indawo yayo ephezulu yokunyibilika, i-thermal conductivity efanelekileyo kunye nokwandiswa kwe-thermal ephantsi kunika ukusebenza kakuhle kwiindawo eziphezulu zokushisa. ISapphire ayisebenzi ngokwekhemikhali kwaye ayinyibiliki emanzini, iiasidi eziqhelekileyo, kunye nealkalis kumaqondo obushushu ukuya kwi-1,000 °C. Iqhele ukusetyenziswa kwiinkqubo ze-laser ye-IR, i-spectroscopy, kunye nezixhobo ezinqabileyo zokusingqongileyo.

Igrafu

Igrafu echanekileyo yi-curve yothumelo lwe-10 mm ubukhulu, i-substrate yesafire engafakwanga

Iingcebiso: ISapphire i-birefringent kancinane, injongo ngokubanzi iifestile ze-IR zidla ngokusikwa ngendlela engakhethiyo ukusuka kwikristale, nangona kunjalo i-orientation ikhethwa kwizicelo ezithile apho i-birefringence ingumba. Ngokuqhelekileyo oku kuhambelana ne-optic axis kwi-90 degrees ukuya kwinqwelomoya kwaye yaziwa ngokuba yi "zero degree" imathiriyeli. Isafire ebonakalayo ayinambala.
