Khwerero Mabowo Dia25.4×2.0mmt Sapphire kuwala mandala mawindo
Zambiri
Mankhwala a safiro ndi okhazikika kwambiri ndipo samawonongeka ndi ma acid ndi alkalis. Kuuma kwa safiro ndikokwera kwambiri, ndi kuuma kwa Mohs kwa 9, kachiwiri kwa diamondi yolimba kwambiri. Ili ndi kufalikira kwabwino kwa kuwala, kutulutsa kwamafuta ndi kutsekemera kwamagetsi, makina abwino amakina ndi makina, ndipo ali ndi mawonekedwe okana kuvala komanso kukana kukokoloka kwa mphepo. Kutentha kwakukulu kwa ntchito ndi 1900 ℃.
Chifukwa zida zapamwamba za safiro za safiro zimakhala ndi kuwala kwabwino mu bandi ya 170nm ~ 6000 nm, ma infrared transmittance pafupifupi sasintha ndi kutentha, kotero zigawo zowoneka bwino ndi ma infrared transmittance optical Mawindo opangidwa ndi safiro opangira apamwamba amapangidwa. miyala yamtengo wapatali ya safiro. Zakhala zikugwiritsidwa ntchito mokwanira pazida zankhondo zowoneka bwino zausiku, doko loyang'ana ma labotale otsika kutentha, zida zolondola kwambiri zoyendera, zakuthambo ndi magawo ena.
Makhalidwe ndi kugwiritsa ntchito safiro
1, safiro yokhala ndi magwiridwe antchito abwino kwambiri, imakhala zida zomwe zimagwiritsidwa ntchito kwambiri ndi oxide substrate (zida zam'munsi)
2, Optical components, galasi woonera, zenera kuwala, kudziwika zenera ndi ntchito yake
3, Sapphire fiber sensor ndi ntchito yake
4, Doped safiro single crystal matenthedwe (kuwala) luminescence zinthu ndi ntchito yake
