Inyathelo Holes Dia25.4×2.0mmt iifestile zeSapphire optical lens
Ulwazi oluneenkcukacha
Iimpawu zeekhemikhali zesafire zizinzile kwaye aziyi kugqweswa yi-acids kunye ne-alkalis. Ubunzima besafire buphezulu kakhulu, kunye nobunzima be-Mohs be-9, okwesibini kuphela kwidayimane enzima kakhulu. Inokuhanjiswa kokukhanya okulungileyo, ukuhanjiswa kwe-thermal kunye nokufakelwa kombane, iipropathi ezilungileyo zoomatshini kunye nezomatshini, kwaye zineempawu zokunganyangeki kunye nokumelana nokukhukuliseka komoya. Ubushushu obuphezulu bokusebenza yi-1900℃.
Ngenxa yokuba umgangatho ophezulu wekristale yesafire yesafire inokuhambisa ukukhanya okuhle kwi-170nm ~ 6000 nm band, ukuhanjiswa kwe-infrared phantse akutshintshi kunye nobushushu, ngoko ke izinto ezibonakalayo kunye ne-infrared transmittance optical Windows eyenziwe ngesafire yokwenziwa ekumgangatho ophezulu. yomgangatho ophezulu wesafire eyenziweyo. Isetyenziswe ngokupheleleyo kwizixhobo ze-infrared zombono wobusuku bomkhosi, izibuko lokujonga elabhoratri lobushushu obuphantsi, izixhobo ezichaneke kakhulu zokuhamba, i-aerospace kunye nezinye iindawo.
Iimpawu kunye nokusetyenziswa kwesafire
I-1, iSapphire kunye nokusebenza kwayo okupheleleyo, ibe yeyona nto isetyenziswa kakhulu kwi-oxide substrate imathiriyeli (izinto eziphantsi komhlaba)
I-2, i-Optical components, i-watch mirror, i-optical window, i-window yokubona kunye nokusetyenziswa kwayo
3, iSapphire fiber sensor kunye nokusetyenziswa kwayo
I-4, I-Doped isafire enye ikristale eshushu (ukukhanya) imathiriyeli ye-luminescence kunye nokusetyenziswa kwayo
