I-alumina yinto eqhelekileyo ye-inorganic non-metallic material, esetyenziswa ngokubanzi kushishino, ulwakhiwo, i-electronics, amayeza kunye nezinye iindawo.

Intshayelelo yeAlumina

I-Alumina ngumgubo omhlophe okanye omhlophe omhlophe kunye ne-molecular formula ye-Al2O3 kunye ne-molecular weight ye-101.96.Yikhompawundi eyenziwe ngealuminiyam kunye neoksijini, enendawo ephezulu yokunyibilika kunye nobunzima.I-alumina yinto ebaluleke kakhulu kwimizi-mveliso ekrwada, esetyenziswa ngokubanzi kwiiseramics, iglasi, i-electronics, amayeza kunye nezinye iindawo.

Iimpawu ezibonakalayo ze-alumina

Iimpawu ezibonakalayo ze-alumina zibandakanya ubukhulu becala, ubunzima, ukuzinza kwe-thermal, iipropati ezibonakalayo kunye nokunye.Ubuninzi be-alumina yi-3.9-4.0g / cm3, ubunzima bubunzima be-Mohs 9, ukuzinza kwe-thermal kuphezulu, kunye ne-melting point yi-2054 ℃.Ukongeza, i-alumina nayo ineempawu ezintle ze-optical kwaye iyinto ebalulekileyo ye-optical material.

Iimpawu zekhemikhali ze-alumina

Iimpawu zeekhemikhali ze-alumina zibandakanya ikakhulu ukusebenza kweekhemikhali ezahlukeneyo, i-asidi kunye ne-alkali.I-alumina idibana ne-asidi yenze i-aluminiyam ityuwa kunye namanzi, kunye ne-alkali yenze i-aluminiyam hydroxide namanzi.Ngelo xesha, i-alumina ineempawu ze-acidic oxides, ezinokusabela ngeekhemikhali ezininzi.

Indlela yokulungiselela i-alumina

Iindlela eziphambili zokulungiselela i-alumina yindlela yeekhemikhali, indlela yomzimba kunye nokunye.Indlela yeekhemikhali ikakhulu ngokusabela kwe-neutralization yetyuwa ye-aluminiyam kunye ne-hydroxide ukufumana i-aluminium hydroxide, kwaye emva koko ngokutshiswa kobushushu obuphezulu ukufumana i-aluminium oxide.Indlela yomzimba ikakhulu ngokubola kwe-ore, i-distillation, icrystallization kunye namanye amanyathelo okufumana i-alumina.

Indawo yesicelo seAlumina

I-alumina isetyenziswa ngokubanzi kushishino, ulwakhiwo, i-elektroniki, amayeza kunye nezinye iinkalo.Kwintsimi yoshishino, i-alumina isetyenziselwa ukwenziwa kweekeramics, iglasi, iingubo kunye nokunye.Kwicandelo lokwakha, i-alumina isetyenziselwa ukwenza iingcango, iifestile, iindonga zamakhethini kunye nokunye.Kwintsimi ye-electronics, i-alumina isetyenziselwa ukuvelisa iibhodi zeesekethe, izixhobo ze-elektroniki, njl. Kwintsimi yamachiza, i-alumina isetyenziselwa ukuveliswa kweziyobisi, izixhobo zonyango kunye nokunye.

Ithemba lophuhliso lwe-alumina

Ngophuhliso oluqhubekayo lwesayensi kunye nethekhnoloji, intsimi yokusetyenziswa kwe-alumina iyanda kwaye ibanzi.Kwixesha elizayo, ngokuphuhliswa ngokukhawuleza kwezinto ezintsha, amandla amatsha kunye nezinye iindawo, imfuno ye-alumina iya kuqhubeka ikhula.Ngelo xesha, kunye nokuphuculwa okuqhubekayo kweemfuno zokukhusela indalo, iteknoloji yokuvelisa i-alumina iya kuqhubeka iphucula, kwaye iindlela zokuvelisa ezinobungane, ezisebenzayo kunye nezonga amandla ziya kuba yindlela yophuhliso.

I-alumina yinto ebalulekileyo ye-inorganic non-metallic, enoluhlu olubanzi lokusetyenziswa kunye nexabiso elibalulekileyo lezoqoqosho.Kwixesha elizayo, kunye nophuhliso olukhawulezayo lwezinto ezintsha kunye namandla amatsha kunye nezinye iindawo, imfuno ye-alumina iya kuqhubeka ikhula, ngelixa iteknoloji yokuvelisa i-alumina iya kuqhubeka iphucula, kwaye yenza igalelo elikhulu kuphuhliso lwabantu.
