Hoʻolauna kumu o ka alumina maʻemaʻe kiʻekiʻe

ʻO ka alumina hoʻomaʻemaʻe kiʻekiʻe he kemika me ke ʻano kemika o Al2O3, me ka maʻemaʻe ʻoi aku ma mua o 99.99% ʻike mākou he alumina maʻemaʻe kiʻekiʻe.

ʻike pono:

Ke kumu molekala: Al2O3

Kaumaha molekula: 102

Ka helu hehee: 2050 ℃

Kaumaha kikoʻī: Al2O3 α Type 2.5-3.95g/cm3

ʻAno kristal: γ ʻAno α ʻano

Nā hiʻohiʻona: ka maʻemaʻe kiʻekiʻe, hiki ke hoʻomalu ʻia ka nui o nā ʻāpana e like me ke kaʻina hana, ka hāʻawi ʻana i ka nui o nā ʻāpana like ʻole, ka pauka ʻono keʻokeʻo

anana kemika:

ʻO ka pauka alumini oxide maʻemaʻe kiʻekiʻe he pauka keʻokeʻo me ka nui o nā ʻāpana like ʻole, maʻalahi ka hoʻopuehu, nā waiwai kemika paʻa, ka emi ʻana o ka wela kiʻekiʻe a me nā waiwai sintering maikaʻi;ʻO ka hoʻololi kiʻekiʻe a me ka haʻahaʻa o ka sodium.ʻO kēia huahana ke kumu kumu kumu no ka hana ʻana i nā huahana pale wela, ʻaʻahu a me ka corrosion-resistant, e like me nā refractories alumini kiʻekiʻe, nā huahana seramika ikaika kiʻekiʻe, nā pahu kukui automotive, nā mea wili holomua a me nā huahana ʻē aʻe, me ka maikaʻi hilinaʻi. , ka helu heheʻe kiʻekiʻe, ka paʻa wela maikaʻi, ka paʻakikī kiʻekiʻe, ke kūpaʻa maikaʻi ʻana i ka lole, ka ikaika mechanical kiʻekiʻe, ka insulation uila maikaʻi a me ka pale ʻana i ka corrosion.Hoʻohana nui ʻia ia i loko o nā ʻano amorphous refractory Mirror polishing o nā mea hoʻonaninani e like me ka refractory castable binder, nā mea hana abrasive wear-resistant, high-purity refractory fiber, special ceramics, electronic ceramics, structural ceramics, stainless steel and granite.Hiki iā ia ke hoʻokō i nā koi o nā mea hoʻohana me nā hoʻohana like ʻole a me nā kūlana kaʻina.Hoʻohana ka alumina i ka alumina ʻoihana mua, alumini hydroxide a me ka ʻenehana hoʻohui.Ma hope o ka calcination hoʻololi haʻahaʻa haʻahaʻa, hoʻohana ʻo ia i ka ʻenehana wili a me ke kaʻina hana e hana i ka pauka alumina hoʻāla ʻia, ka mea i hōʻike ʻia e ka hana nui a me ka nui o ka nui.He mea kūpono ia no nā huahana i hoʻohālikelike ʻia a me nā refractory amorphous e like me ka refractory castables, plastic, repair materials, gunning materials and coating materials.He hana koʻikoʻi ia i ka hoʻomaikaʻi ʻana i ka ikaika kiʻekiʻe-mehana a me ka pale ʻana i ka corrosion o nā refractory

Ke noi nui

1） Mea luminescent: hoʻohana ʻia ma ke ʻano he kumu nui o ka phosphor trichromatic phosphor, lōʻihi afterglow phosphor, PDP phosphor a me ka phosphor alakaʻi;

2） ʻO nā seramika alohilohi: hoʻohana ʻia e like me nā paipu fluorescent o nā kukui sodium paʻa kiʻekiʻe a me nā puka makani hoʻomanaʻo heluhelu-wale i hiki ke hoʻonohonoho uila;

3） Hoʻokahi aniani: hoʻohana ʻia no ka hana ʻana i ka ruby, sapphire a me yttrium alumini garnet;

4）Ka ikaika kiʻekiʻe a me nā seramika alumini kiʻekiʻe: hoʻohana ʻia no ka hana ʻana i nā substrates integrated circuit, nā mea hana ʻoki a me nā crucibles maʻemaʻe kiʻekiʻe;

5）Abrasive: hoʻohana ʻia no ka hana ʻana i ke aniani, metala, semiconductor a me ka plastic;

6）Diaphragm: hoʻohana ʻia no ka hana ʻana i ka uhi diaphragm o ka pā lithium;

7） ʻO nā mea ʻē aʻe: hoʻohana ʻia e like me ka uhi ʻana, adsorbent, catalyst a me catalyst carrier, vacuum coating, nā mea aniani kūikawā, composites, resin filler, bioceramics, etc.
