Nā puka makani aniani optical Sapphire Dia25.4 × 2.0mmt Nā lua ʻanuʻu Dia25.4 × 2.0mmt
ʻIke kikoʻī
He paʻa loa nā waiwai kemika o ka sapeiro a ʻaʻole i pala i nā waikawa a me nā alkalis. Kiʻekiʻe loa ka paʻakikī o ka sapeiro, me ka paʻakikī Mohs o 9, ʻo ia ka lua ma hope o ka daimana paʻakikī loa. Loaʻa iā ia ka hoʻoili mālamalama maikaʻi, ka conductivity thermal a me ka insulation uila, nā waiwai mechanical a me nā mechanical maikaʻi, a he mau ʻano o ke kūpaʻa ʻana i ka ʻaʻahu a me ke kūpaʻa ʻana i ka makani. ʻO ka mahana hana kiʻekiʻe loa he 1900℃.
Ma muli o ka hoʻoili māmā maikaʻi ʻana o ka mea kristal sapeiro artificial kiʻekiʻe ma ka hui 170nm ~ 6000 nm, ʻaneʻane ʻaʻole loli ka hoʻoili infrared me ka mahana, no laila ʻo nā ʻāpana optical a me nā puka makani optical transmittance infrared i hana ʻia me ka sapeiro artificial kiʻekiʻe i hana ʻia me ka sapeiro artificial kiʻekiʻe. Ua hoʻohana piha ʻia i nā lako infrared ʻike pō koa, nā puka nānā keʻena haʻahaʻa haʻahaʻa, nā mea hana kiʻekiʻe no ka hoʻokele, aerospace a me nā ʻoihana ʻē aʻe.
Nā ʻano a me ka hoʻohana ʻana o ka sapphire
1, ʻo Sapphire me kāna hana piha maikaʻi loa, lilo i nā mea substrate oxide i hoʻohana nui ʻia (nā mea substrate)
2, Nā ʻāpana optical, aniani wati, puka makani optical, puka makani ʻike a me kāna noi
3, ʻO ka sensor fiber Sapphire a me kāna noi
4, ʻO ka mea luminescence thermal (mālamalama) sapphire hoʻokahi kristal a me kāna noi
