Sapphire (Al2O3)
Sapphire (Al2O3waa oksijiin aluminium crystal ah (Al2O3) oo leh adkaanta Mohs ee 9, waa mid ka mid ah qalabka ugu adag.Adkeysigan xad dhaafka ah ee sapphire ayaa adkeynaya in la nadiifiyo iyadoo la adeegsanayo farsamooyinka caadiga ah.Dhammaystirka tayada sare ee indhaha ee sapphire mar walba suurtagal maaha.Maadaama Sapphire uu yahay mid aad u adkeysi leh oo leh awood farsamo oo wanaagsan, had iyo jeer waxaa loo isticmaalaa sida alaabta daaqada halkaasoo caabbinta xoqan looga baahan yahay.Barta dhalaalka sare, socodka kulaylka wanaagsan iyo fidinta kulaylka hooseeya waxay bixiyaan waxqabad heer sare ah jawiga heerkulka sare.Sapphire waa kiimiko ahaan aan firfircoonayn oo aan lagu milmi karin biyaha, asiidhka caadiga ah, iyo alkalis heerkulka ilaa 1,000 ° C.Waxaa caadi ahaan loo isticmaalaa nidaamyada laysarka IR, spectroscopy, iyo qalabka deegaanka ee adag.

Talooyin: Sapphire wax yar ayuu ka duwan yahay, ujeedada guud ee daaqadaha IR waxaa badanaa loo gooyaa si aan kala sooc lahayn oo laga soo bilaabo crystal, si kastaba ha ahaatee hanuuninta ayaa loo doortaa codsiyo gaar ah halkaasoo birefringence ay tahay arrin.Caadi ahaan tani waxay la socotaa dhidibka indhaha ee 90 darajo ee diyaaradda oogada waxaana loo yaqaannaa walxaha "eber degree".Sapphire-ka synthetic ma laha midab.
Si aad u hesho xog faahfaahsan oo qoto dheer, fadlan eeg buugaag optics-kayaga si aad u aragto xulashadayada dhamaystiran ee muraayadaha laga sameeyay sapphire.
