99.999% Al2O3 safire boule monocrystal thepa e bonaletsang
Safira ke thepa e ikhethang e sebelisoang haholo indastering kajeno. Safira ke ntho e thata ka ho fetisisa, e latelang daemane feela, e nang le boima ba Mohs ba 9. Ha e hanele feela ho ngoatheloa le ho taboha, empa hape le lik'hemik'hale tse ling tse kang li-acid le alkali, e leng se etsang hore e be matla haholo ho feta lisebelisoa tse ling tsa optical. Ka hona, e loketse bakeng sa ts'ebetso ea semiconductor le lik'hemik'hale. Ka ntlha ea ho qhibiliha ea hoo e ka bang 2050°C, safira e ka sebelisoa lits'ebetsong tsa mocheso o phahameng ho fihlela ho 1800°C, 'me botsitso ba eona ba mocheso le bona bo phahame ho feta ba thepa efe kapa efe ea optical. Ho phaella moo, safira e bonaletsa ho tloha ho 180nm ho isa ho 5500nm, 'me mefuta ena e mengata ea thepa ea optical e etsa safira hore e be thepa e ntle ka ho fetisisa bakeng sa litsamaiso tsa optical tsa infrared le ultraviolet. Qetellong empa e se ea bohlokoa, safira ke thepa e tsebahalang indastering ea mabenyane, e khetholloang ka ho khetheha ka bohloeki ba eona bo phahameng, phetiso ea leseli le thata. 'Mala oa safira o ka fetoloa ho latela litlhoko tse fapaneng, o fa bareki mefuta e mengata ea likhetho.
