Uruganda rwabigenewe rutunganya imashini ya safiro
Safiro ifite ubukana bwa Mohs 9, icya kabiri nyuma ya diyama, kandi irwanya kwambara neza. Muri icyo gihe, ifite imiti ihamye kandi irashobora kurwanya ruswa hafi ya aside yose hamwe na alkali. Byongeye kandi, ubushyuhe ntarengwa bwa safiro ni 2060 ℃. Kubera ibyiza byavuzwe haruguru bya safiro, safiro ikoreshwa mubikoresho nibikoresho, bishobora kuzamura cyane ubuzima bwa serivisi no kwihanganira ibidukikije bikaze.
Ibice bya safiro akenshi bifite imiterere igoye kandi bisabwa neza. Turashobora guhitamo imiterere itandukanye dukurikije ibishushanyo byabakiriya. Dufite gukata neza, gusya, gusya no kugerageza ibikoresho kugirango tumenye neza ko buri gicuruzwa cyujuje ibyifuzo byabakiriya.
Uburyo bukuru bwo gushiraho
Ibikoresho
Safiro ni kristu imwe ya aluminium oxyde (Al2O3). Nibimwe mubikoresho bikomeye. Safiro ifite uburyo bwiza bwo kohereza hejuru igaragara, kandi hafi ya IR. Yerekana imbaraga za mashini nyinshi, kurwanya imiti, ubushyuhe bwumuriro hamwe nubushyuhe bwumuriro. Bikunze gukoreshwa nkibikoresho byidirishya mubice byihariye nkikoranabuhanga ryikirere aho bisabwa gushushanya cyangwa ubushyuhe bwo hejuru.
