Oghere Nzọụkwụ Dia25.4 × 2.0mmt windo oghere anya sapphire
Ozi zuru ezu
Njirimara kemịkalụ nke sapphire siri ike nke ukwuu, asịd na alkalis anaghịkwa emebi ya. Ike sapphire dị elu nke ukwuu, ike Mohs bụ 9, nke abụọ karịa dayamọnd kacha sie ike. O nwere ezigbo nnyefe ìhè, ike okpomọkụ na mkpuchi eletriki, ezigbo ihe onwunwe mekaniki na mekaniki, ma nwee njirimara nke iguzogide iyi na iguzogide mbuze ifufe. Oke okpomọkụ ọrụ kachasị bụ 1900℃.
Ebe ọ bụ na ihe kristal sapphire e ji aka rụọ nke dị elu nwere ezigbo nnyefe ìhè na eriri 170nm ~ 6000 nm, nnyefe infrared anaghị agbanwe agbanwe ka okpomọkụ dị, yabụ ihe ndị dị n'ime ya na windo nnyefe infrared nke e ji sapphire e ji aka rụọ nke dị elu mee bụ sapphire e ji aka rụọ nke dị elu. Ejirila ya mee ihe nke ọma na ngwa infrared ọhụụ abalị nke ndị agha, ọdụ ụgbọ mmiri nlele ụlọ nyocha dị ala, ngwa dị elu maka ịnyagharị, ụgbọelu na ubi ndị ọzọ.
Njirimara na ojiji nke sapphire
1, Sapphire nwere arụmọrụ zuru oke ya, ghọrọ ihe ndị e ji oxide substrate eme ihe n'ọtụtụ ebe (ihe ndị e ji substrate mee)
2, Ihe ndị dị na ngwa anya, enyo elekere, windo anya, windo nchọpụta na ngwa ya
3, ihe mmetụta eriri Sapphire na ngwa ya
4, ihe e ji ekpo ọkụ sapphire otu kristal mee nke e ji doped mee na ojiji ya
