I\u0161laisvinkite neprilygstam\u0105 grynum\u0105 ir na\u0161um\u0105 su aliuminio oksido milteliais<\/h1>\n

Aliuminis (chemin\u0117 formul\u0117 Al\u2082O\u2083) yra itin universalus pramoninis med\u017eiaga, naudojama \u012fvairiose srityse \u2013 nuo keramikos ir abrazyv\u0173 iki katalizatori\u0173 ne\u0161ikli\u0173. M\u016bs\u0173 auk\u0161to grynumo aliuminio milteliai puikiai tinka pa\u017eangiausiems puslaidininki\u0173 \u012frenginiams, kuriems reikalingas i\u0161skirtinis \u0117sdinimo grynumas ir na\u0161umas, taip pat kitoms kritin\u0117ms taikymo sritims, kuriose b\u016btinas ma\u017eas ter\u0161al\u0173 kiekis ir puikus atsparumas nusid\u0117v\u0117jimui.<\/p>\n

Auk\u0161tas grynumas<\/h2>\n

Alumina yra pagrindin\u0117 med\u017eiaga, naudojama daugelyje auk\u0161tos kokyb\u0117s taikym\u0173, ta\u010diau keramini\u0173 aliuminio oksido gamini\u0173 savyb\u0117s priklauso nuo j\u0173 grynumo. Naudojant auk\u0161to grynumo aliuminio oksid\u0105 (HPA) u\u017etikrinama, kad keramikoje b\u016bt\u0173 kuo ma\u017eiau ter\u0161al\u0173 ir priemai\u0161\u0173, o tai leid\u017eia u\u017etikrinti geresn\u012f \u0161ilumos valdym\u0105 ir patobulinti radijo da\u017eni\u0173 (RF) taikymus.<\/p>\n

HPA gaminamas i\u0161tirpinant ir i\u0161gryninant aliuminio hidroksid\u0105, kuris naudojamas kaip \u017ealiava, o v\u0117liau \u2013 kalcinuojant, siekiant u\u017etikrinti auk\u0161tesn\u012f grynumo lyg\u012f. \u0160is procesas kartojamas tol, kol pasiekiamas norimas grynumo lygis, ir taip gaunami aliuminio oksido milteliai, pasi\u017eymintys daugeliu pageidaujam\u0173 savybi\u0173, toki\u0173 kaip cheminis stabilumas, auk\u0161ta lydymosi temperat\u016bra, mechaninis stiprumas ir kietumas.<\/p>\n

Didelis \u0161ilumos laidumas<\/h2>\n

Sferiniai aliuminio oksido milteliai pasi\u017eymi i\u0161skirtiniu \u0161ilumos laidumu, tod\u0117l yra ideali med\u017eiaga, skirta naudoti kaip laid\u017eiosios pagalv\u0117l\u0117s ir lak\u0161tai elektroniniuose prietaisuose. J\u0173 puikios \u0161ilumos perdavimo ir i\u0161sklaidymo savyb\u0117s padeda i\u0161vengti perkaitimo bei d\u0117l perkaitimo kylan\u010di\u0173 \u012frangos gedim\u0173.<\/p>\n

Aluminosio oksido milteliai pasi\u017eymi pastoviu daleli\u0173 dyd\u017eio pasiskirstymu, tod\u0117l jie tinka \u012fvairiems poliravimo darbams ir padeda reguliuoti poliravimo greit\u012f, u\u017etikrinant tolyg\u0173 pavir\u0161iaus nu\u0161lifavim\u0105. D\u0117l savo universalumo aluminosio oksidas taip pat yra nepakei\u010diama sudedamoji dalis \u012fvairiose auk\u0161tos kokyb\u0117s keramikos srityse, pavyzd\u017eiui, filtravimo sistemose ir adityviojoje gamyboje.<\/p>\n

Aliuminio oksido milteliai taip pat gali b\u016bti naudojami metalini\u0173 pavir\u0161i\u0173 dengimui ir u\u017etikrina puik\u0173 \u0161ilumos i\u0161sklaidym\u0105 elektroniniuose moduliuose ir \u012frenginiuose, pavyzd\u017eiui, elektroniniuose moduliuose ir \u012frenginiuose. Aliuminis da\u017enai naudojamas kaip puiki \u0161ilum\u0105 gerai laid\u017ei danga spausdintin\u0117ms plok\u0161t\u0117ms ir integrini\u0173 grandyn\u0173 korpusams d\u0117l savo auk\u0161to \u0161ilumos laidumo, taip pat \u017eemos lydymosi temperat\u016bros ir gar\u0173 sl\u0117gio \u2013 tai rei\u0161kia, kad jis gali atlaikyti auk\u0161tesnes darbin\u0117s temperat\u016bras, kuri\u0173 reikalauja \u0161ios dangos.<\/p>\n

Puikus atsparumas nusid\u0117v\u0117jimui<\/h2>\n

D\u0117l vienodo dyd\u017eio aliuminio oksido abrazyvini\u0173 daleli\u0173 galima kontroliuoti poliravimo greit\u012f ir u\u017etikrinti lyg\u0173 pavir\u0161i\u0173, be to, \u0161i med\u017eiaga yra ideali pa\u017eangiosios technin\u0117s keramikos gamybai, naudojamai tokiose pramon\u0117s \u0161akose kaip aviacijos ir kosmoso pramon\u0117, automobili\u0173 pramon\u0117 bei vartojimo preki\u0173 gamyba. Aliuminio oksido ATC taikymo sritys apima atbrail\u0173 \u0161alinim\u0105, poliravim\u0105, apna\u0161\u0173 pa\u0161alinim\u0105, form\u0173 valym\u0105, paruo\u0161iam\u0105j\u012f apdorojim\u0105 ir metalo sm\u0117liavim\u0105.<\/p>\n

\u0160io tyrimo tikslas buvo padidinti aliuminio oksido keramikos atsparum\u0105 dilimui, naudojant nedidelius Gd\u2082O\u2083 kiekius. Buvo paruo\u0161ti aliuminio oksido milteliai, kuri\u0173 sud\u0117tyje buvo skirtingas Gd\u2082O\u2083 procentinis kiekis; v\u0117liau, vadovaujantis Kinijos pramon\u0117s standartu, buvo \u012fvertinti j\u0173 t\u016brinis tankis, daleli\u0173 dyd\u017eio pasiskirstymas, morfologija ir gr\u016bd\u0173 rib\u0173 sukibimas, o po to pagal Kinijos standartus i\u0161matuotas dilimo greitis. Rezultatai parod\u0117, kad Gd\u2082O\u2083 prid\u0117jimas tur\u0117jo teigiam\u0105 poveik\u012f faziniams per\u0117jimams, susiaurino gr\u016bd\u0173 ribas ir sustiprino gretim\u0173 gr\u016bd\u0173 tarpusavio s\u0105sajas, d\u0117l ko aliuminio oksido keramikos atsparumas dilimui, palyginti su ankstesniais modeliais, \u017eymiai pager\u0117jo; dilimo greitis did\u0117jo paraboliniu b\u016bdu did\u0117jant Gd\u2082O\u2083 kiekiui su kiekvienu papildomu procentiniu padid\u0117jimu.<\/p>","protected":false},"excerpt":{"rendered":"
