Aliuminio oksido milteliai yra neatskiriama daugelio keramikos gamini\u0173 sud\u0117tin\u0117 dalis. Jie naudojami plyteli\u0173 gamybai ir atspari\u0173 dilimui keramikos gaminiams gaminti; be to, jie tarnauja kaip katalizatoriaus ne\u0161iklis. Aliuminio oksidas gaunamas sumai\u0161ant aliuminio hidroksid\u0105 su vandeniu ir kaitinant j\u012f auk\u0161toje temperat\u016broje. Kalcinuot\u0105 aliuminio oksid\u0105 galima skirstyti pagal kristal\u0173 dyd\u012f ir natrio kiek\u012f. Med\u017eiagos, kuri\u0173 natrio kiekis yra ma\u017eesnis, tinka elektronikos pramon\u0117je arba keramini\u0173 substrat\u0173 gamybai.<\/p>\n

In\u017einieriai gali pasinaudoti \u0161iais bandymais, kad tiksliai suderint\u0173 recept\u016bras pagal konkre\u010dius taikymo poreikius ir \u012fvertint\u0173 poveik\u012f aplinkai; be to, jie gali nustatyti ugniai atspari\u0173 med\u017eiag\u0173 tinkamum\u0105 konkre\u010dioms aplinkoms, atsi\u017evelgdami \u012f tokius veiksnius kaip atsparumas terminiam \u0161okui, cheminis suderinamumas su i\u0161lydytais metalais ir \u0161lakais bei matmen\u0173 stabilumas.<\/p>\n
Aliuminis yra nepakei\u010diamas katalizatoriaus ne\u0161iklis d\u0117l savo cheminio inerti\u0161kumo ir akytos strukt\u016bros. \u0160i savyb\u0117 leid\u017eia jam skatinti chemines reakcijas naftos chemijos pramon\u0117je, taip pat prisid\u0117ti prie aplinkos apsaugos.\u00a0Akytoji aliuminio oksido med\u017eiaga gali b\u016bti gaminama hidroterminio sintez\u0117s b\u016bdu, reaguojant aliuminio hidroksidui su vandeniu u\u017edarame inde esant auk\u0161tam sl\u0117giui ir temperat\u016brai, taip susidaro ypa\u010d grynos nanodyd\u017eio dalel\u0117s, turin\u010dios konkre\u010dias formas ir dyd\u017eius bei atitinkan\u010dios tam tikrus standartus. \u0160ios reakcijos rezultatas \u2013 labai grynos aliuminio oksido dalel\u0117s, turin\u010dios konkre\u010dias formas ir dyd\u017eius bei atitinkan\u010dios tikslias specifikacijas.
