99.999% Al2O3 sapphire boule monocrystal walax hufan
Sapphire waa walax gaar ah oo si caadi ah looga isticmaalo warshadaha maanta. Sapphire waa walaxda ugu adag, oo ka dambeysa dheemanka, kaas oo leh adkeysi Mohs oo ah 9. Ma aha oo kaliya inay u adkaysato xoqidda iyo xoqidda, laakiin sidoo kale kiimikooyinka kale sida asiidhyada iyo alkalis, taasoo ka dhigaysa mid aad uga xoog badan agabka kale ee indhaha. Sidaa darteed, waxay ku habboon tahay habaynta semiconductor iyo kiimikada. Iyada oo leh dhibic dhalaalaysa oo qiyaastii ah 2050°C, sapphire waxaa loo isticmaali karaa codsiyada heerkulka sare ilaa 1800°C, xasilloonideeda kulaylkana sidoo kale way ka sarreysaa tan walxaha kale ee indhaha. Intaa waxaa dheer, sapphire waa mid hufan laga bilaabo 180nm ilaa 5500nm, noocyadan kala duwan ee sifooyinka hufnaanta indhaha ayaa sapphire ka dhigaya agabka ugu fiican ee nidaamyada indhaha ee infrared iyo ultraviolet. Ugu dambeyntii, sapphire sidoo kale waa walax caan ah oo ka jirta warshadaha dahabka, oo si gaar ah loogu garto daahirnimadeeda sare, gudbinta iftiinka iyo adkaanta. Midabka sapphire waa la beddeli karaa iyadoo loo eegayo shuruudaha kala duwan, taasoo macaamiisha siinaysa fursado kala duwan.
