Pauka ʻokikene aluminika Alpha-al2o3 99.99% Maʻemaʻe
ʻO ka pauka Alpha-alumina (α-Al2O3), i ʻike nui ʻia ʻo ka pauka alumini oxide, he mea hana maʻalahi ia me nā ʻano hana like ʻole i nā ʻoihana e like me nā keramika, nā mea hoʻopaʻa, nā mea hoʻoheheʻe, nā mea hoʻouluulu, a me nā mea hou aku. Eia kekahi mau kikoʻī maʻamau no ka pauka alpha-Al2O3
Ka Hoʻohui Kemika:
ʻOkiuma aluminika (Al2O3): ʻO 99% a ʻoi aku paha ka maʻamau.
Ka nui o ka ʻāpana:
Hiki ke ʻokoʻa ka hoʻolaha ʻana o ka nui o nā ʻāpana ma muli o nā koi noi kikoʻī.
Hiki i ka nui o nā ʻāpana awelika ke ʻano mai kahi sub-micron a i kekahi mau microns.
Hāʻawi nā pauka ʻoi aku ka maikaʻi o ka nui o nā ʻāpana i ka ʻilikai kiʻekiʻe a me ka reactivity.
Waihoʻoluʻu:
Keʻokeʻo maʻamau, me ke kiʻekiʻe o ka maʻemaʻe.
ʻAno kristal:
Loaʻa iā Alpha-alumina (α-Al2O3) kahi ʻano kristal hexagonal.
ʻĀpana ʻIli Kūikawā:
ʻO ka maʻamau ma ka pae o 2 a 20 m2/g.
Hāʻawi nā pauka ʻili kiʻekiʻe i ka hoʻonui ʻana i ka reactivity a me ka uhi ʻili.
Maʻemaʻe:
Loaʻa pinepine nā pauka alpha-Al2O3 kiʻekiʻe me ka liʻiliʻi o nā haumia.
ʻO ka pae maʻemaʻe he 99% a ʻoi aku paha.
Ka nui o ka nui:
Hiki ke ʻokoʻa ka nui o ka pauka alpha-Al2O3 ma muli o ke kaʻina hana kikoʻī a i ʻole ka papa.
ʻO ka maʻamau, aia ia mai 0.5 a 1.2 g/cm3.
Paʻa Wela:
Hōʻike ka pauka Alpha-Al2O3 i ke kūpaʻa wela maikaʻi loa a me ke kiko heheʻe kiʻekiʻe.
Kiko heheʻe: Ma kahi o 2,072°C (3,762°F).
Paʻakikī:
Ua ʻike ʻia ka pauka Alpha-Al2O3 no kona paʻakikī kiʻekiʻe.
Paʻakikī Mohs: Ma kahi o 9.
Ka Inertness Kemika:
He inert kemika ka pauka Alpha-Al2O3 a ʻaʻole ia e pane me ka hapa nui o nā kemika.
He kūpaʻa ia i nā waikawa a me nā alkalis.
He mea nui e hoʻomaopopo he ʻokoʻa paha nā kikoʻī kikoʻī o ka pauka alpha-Al2O3 ma waena o nā mea hana a me nā papa kikoʻī. No laila, he mea kūpono ke nānā i ka pepa ʻikepili huahana a nīnau paha i ka mea hoʻolako no ka ʻike kikoʻī a me nā koi kikoʻī no kāu noi i manaʻo ʻia.
1. Nā mea Luminescent: nā phosphors trichromatic honua kakaikahi i hoʻohana ʻia ma ke ʻano he mea nui ka phosphor afterglow lōʻihi, PDP phosphor, LED phosphor;
2. Nā keramika moakaka: hoʻohana ʻia e like me nā ʻōmole fluorescent no ke kukui sodium kiʻekiʻe, ka puka makani hoʻomanaʻo heluhelu-wale nō hiki ke hoʻonohonoho uila ʻia;
3.Single Crystal: no ka hana ʻana o ka ruby, sapeiro, yttrium aluminum garnet;
4.High ikaika kiʻekiʻe alumina seramika: e like me ke substrate i hoʻohana ʻia i ka hana ʻana o nā kaapuni i hoʻohui ʻia, nā mea ʻokiʻoki a me ka ipu hoʻoheheʻe maʻemaʻe kiʻekiʻe;
5.Abrasive: hana i ka abrasive o ke aniani, metala, semiconductor a me ka plastic;
6.Diaphragm: Noi no ka hana ʻana o ka uhi hoʻokaʻawale pākahiko lithium;
7. ʻĒ aʻe: ma ke ʻano he uhi hana, nā adsorbents, nā mea hoʻoulu a me nā kākoʻo mea hoʻoulu, ka uhi ʻana i ka vacuum, nā mea aniani kūikawā, nā mea hui pū ʻia, ka mea hoʻopiha resin, nā bio-ceramics etc.
Kāu Nīnau
Inā he mau nīnau kāu. E ʻoluʻolu e hoʻokaʻaʻike mai iā mākou.
