99.999% Al2O3 safiro boule monocrystal zinthu zowonekera

Safira ndi chinthu chapadera chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale masiku ano. Safira ndi chinthu chovuta kwambiri, chachiwiri kwa diamondi, chomwe chili ndi kuuma kwa Mohs kwa 9. Sikuti chimangolimbana ndi mikwingwirima ndi kusweka, komanso ndi mankhwala ena monga ma acid ndi alkali, zomwe zimapangitsa kuti chikhale cholimba kwambiri kuposa zinthu zina zowunikira. Chifukwa chake, ndi chabwino kwambiri pokonza zinthu za semiconductor ndi mankhwala. Ndi kutentha kwa pafupifupi 2050°C, safiro ingagwiritsidwe ntchito kutentha kwambiri mpaka 1800°C, ndipo kukhazikika kwake kutentha ndikwapamwamba kuposa kwa zinthu zina zowunikira. Kuphatikiza apo, safiro ndi yowonekera kuyambira 180nm mpaka 5500nm, ndipo mawonekedwe osiyanasiyana a kuwala amapangitsa safiro kukhala chinthu chabwino kwambiri pamakina owunikira a infrared ndi ultraviolet. Chomaliza koma chofunikira kwambiri, safiro ndi chinthu chodziwika bwino mumakampani odzikongoletsera, chodziwika bwino ndi kuyera kwake kwakukulu, kutumiza kuwala ndi kuuma kwake. Mtundu wa safiro ukhoza kusinthidwa malinga ndi zofunikira zosiyanasiyana, kupatsa makasitomala zosankha zosiyanasiyana.
