Hana ʻia ka pauka silicate alumini synthetic ma o nā kaʻina hana kemika. ʻO ke ʻano sol-gel, no ka laʻana, pili i ka hoʻopili ʻana i nā paʻakai alumini (e like me ka alumini nitrate) me nā precursors i loaʻa ka silicon (e like me ka tetraethyl orthosilicate) i loko o kahi hopena wai. Hoʻokumu kēia hopena i kahi gel, a laila hoʻomaloʻo ʻia a calcined i nā mahana kiʻekiʻe (800 - 1200°C) e hana i ka pauka grained maikaʻi. ʻO ka synthesis hydrothermal kekahi ala ʻē aʻe, kahi e pane ai nā mea maka ma lalo o ke kaomi kiʻekiʻe a me ka mahana i loko o ka wai, e hiki ai ke kaohi pololei i ka nui o ka ʻāpana a me ke ʻano.

Hōʻike ka pauka silicate alumini i ke kūpaʻa wela kūikawā, me kahi kiko heheʻe e ʻoi aku ana ma mua o 1600°C, e kūpono ai no nā noi wela kiʻekiʻe. ʻO kona kūpaʻa kemika kiʻekiʻe e kūʻē i ka palaho mai ka hapa nui o nā waikawa a me nā alkalis, ʻoiai ʻo kona conductivity wela haʻahaʻa e hāʻawi i ka insulation maikaʻi loa. ʻO ka nui o ka ʻāpana o ka pauka, mai ka sub-micrometer a i kekahi mau micrometer, e hoʻohuli i kona reactivity a me ka dispersibility. ʻO nā ʻano i hoʻololi ʻia i ka ʻili, i mālama ʻia me nā silanes a i ʻole polymers, e hoʻonui i ka launa pū me nā mea ʻē aʻe.

I loko o nā keramika, lawelawe ia ma ke ʻano he mea nui i loko o ka porcelain, stoneware, a me nā refractories, e hoʻomaikaʻi ana i ka ikaika mechanical a me ka hōʻemi ʻana i ka hoʻonui wela. No ka laʻana, i loko o nā uhi umu, kū nā refractories i hoʻokumu ʻia i ka silicate alumini i nā mahana a hiki i 1800°C. I ka hana pepa, hana ia ma ke ʻano he pigment uhi, e hoʻonui ana i ka ʻōlinolino, ka opacity, a me ka hiki ke paʻi. Hoʻohana ka ʻoihana hoʻonaninani iā ​​​​ia ma ke ʻano he mea hoʻopiha i nā pauka a me nā kirīmi, e hāʻawi ana i kahi ʻano palupalu a me nā waiwai omo aila.
