| Paʻakikī | 9 ma ka unahi Mohs, e hāʻawi ana i ke kūpaʻa maikaʻi loa i ke ʻoki ʻana a me ke komo ʻana, ʻo ka lua wale nō i ka daimana |
| Ka Hoʻokele Wela | 46 W/m·K (ma 100°C), e hiki ai ke hoʻopuehu pono i ka wela |
| Kiko Heheʻe | 2,040°C (3,704°F), e hāʻawi ana i ke kū'ē kūikawā i nā mahana koʻikoʻi |
| Mahana Hana Kiʻekiʻe Loa | Hiki ke hana mau i nā mahana a hiki i 1,600°C (2,912°F) |
| Ka helu hoʻonui wela | 5.3 × 10⁻⁶ /°C (0-1000°C), e hōʻoiaʻiʻo ana i ke kūpaʻa o ka dimensional ma lalo o nā fluctuations thermal kiʻekiʻe |
| ʻIneki Refractive | 1.76 (ma 0.589 μm), e hāʻawi ana i nā waiwai optical maikaʻi loa i kūpono no ka hoʻohana ʻana i nā noi UV a i IR |
| Ka moakāka | Ma luna o 85% ka moakāka ma waena o nā nalu mai 0.3 a 5.5 μm |
| Ke kū'ē kemika | Kūpaʻa loa i nā waikawa, alkalis, a me ka hapa nui o nā mea ʻino kemika |
| Ka nui o ka paʻa | 3.98 g/cm³, e hōʻoiaʻiʻo ana i ka kūpaʻa o ke kūkulu ʻana |
| Modulus o Young | 345 GPa, e hāʻawi ana i ka paʻakikī mechanical kiʻekiʻe a me ka lōʻihi |
| Hoʻokaʻawale Uila | ʻO nā waiwai dielectric maikaʻi loa, e kūpono ana no nā noi insulating i nā mea uila |
| Nā ʻenehana hana | Hana ʻia me ka hoʻohana ʻana i nā ʻano hana Czochralski (CZ) a me Kyropoulos (KY) holomua no ka pololei a me ka hilinaʻi |
| Nā noi | Hoʻohana pinepine ʻia i ka hana semiconductor, nā umu wela kiʻekiʻe, nā optics, aerospace, a me nā ʻoihana kemika |
ʻO ka paipu sapeiro XINKEHUI waiwai paipu
Hoʻohana Huahana
Hoʻohana nui ʻia nā ʻōmole sapphire i nā ʻoihana hana kiʻekiʻe e like me ka hana semiconductor, aerospace, optics, a me ka ʻenekinia kemika. ʻO ko lākou hiki ke kū i nā mahana koʻikoʻi (a hiki i 1,600°C), me ke kūpaʻa kemika koʻikoʻi i nā waikawa a me nā alkalis, e kūpono ai lākou no nā umu wela kiʻekiʻe a me nā wahi ʻino. Eia kekahi, ʻo ko lākou transparency kiʻekiʻe ma waena o nā nalu UV a IR e waiwai nui ai lākou i nā ʻōnaehana optical. He mea koʻikoʻi nō hoʻi ka ikaika mechanical kiʻekiʻe a me ka conductivity thermal o ka ʻōmole sapphire no nā noi kahi e pono ai ka lōʻihi a me ka hoʻokuʻu ʻana i ka wela, e like me nā mea uila a me nā ʻōnaehana mana.
Hōʻuluʻulu Manaʻo Holoʻokoʻa
ʻO ka paipu sapeiro, i hana ʻia mai ka sapeiro kristal hoʻokahi Al₂O₃ maʻemaʻe 99.999%, he mea kūikawā ia i hoʻolālā ʻia no ka hoʻohana ʻana i nā ʻoihana hana kiʻekiʻe e like me semiconductors, aerospace, optics, a me ka ʻenekinia kemika. Me ka paʻakikī o 9 ma ka unahi Mohs, hāʻawi ia i ke kūpaʻa ʻana i ke kahakaha a me ka ikaika mechanical. Hiki iā ia ke hana i nā wahi koʻikoʻi me nā mahana a hiki i 1,600°C, e kūpono ana no nā umu wela kiʻekiʻe a me nā hoʻonohonoho corrosive ma muli o kona kūpaʻa kemika maikaʻi loa.
Eia kekahi, ʻo ka conductivity thermal o ka paipu sapphire o 46 W/m·K e hōʻoiaʻiʻo ana i ka hoʻopuehu wela maikaʻi, ʻoiai ʻo kona transparency kiʻekiʻe ma waena o nā nalu UV a IR e kākoʻo ana i nā noi optical koʻikoʻi. I hui pū ʻia me kāna mau waiwai dielectric maikaʻi loa, he hopena paʻa kēia huahana no nā mea uila, nā ʻōnaehana mana, a me nā optics. Me ke kūpaʻa kiʻekiʻe, ke kūpaʻa, a me ka hana, hāʻawi nā paipu sapphire i ka hilinaʻi ma kekahi o nā ʻano ʻoihana a me nā ʻenehana koi nui loa.
