Munyaya yesainzi yezvinhu, tinogara tichitsvaga zvinhu zvitsva zvine hunhu hwakanaka uye kugadzikana. Pakati pazvo, alumina ceramics inoshandiswa zvakanyanya muminda yakasiyana-siyana nekuda kwehunhu hwayo hwakanaka hwepanyama uye hwemakemikari, pamwe nekudzivirira kupisa kwakanyanya uye kuramba ngura. Nhasi, ngatinyatsoongorora kugadzikana kwemakemikari kwealumina ceramics.
Chekutanga, kugadzikana kwemakemikari ezviumbwa zvesimbi zvealuminainonyanya kuratidzwa mukudzivirira kwayo maasidhi mazhinji, mabhesi uye ma oxidants. Izvi zvinodaro nekuti chimiro che alumina ceramics chakasimba uye chisungo chiri pakati pemamorekuru chakasimba, izvo zvinoita kuti ikwanise kuchengetedza chimiro chayo chepakutanga uye hunhu hwayo munzvimbo dzakaoma. Kugadzikana uku kunoita kuti alumina ceramics ishandiswe zvakanyanya mumakemikari, peturu, simbi nedzimwe nzvimbo.
Chechipiri, kugadzikana kwemakemikari e-alumina ceramics kunoratidzwawo muhunhu hwayo hwe-antioxidant. Kana mamiriro ekupisa kwakanyanya, zvinhu zvakawanda zvinosangana neokisijeni, zvichikonzera kuti chimiro chazvo uye hunhu hwazvo zvichinje. Zvisinei, Alumina ceramics inoramba yakagadzikana munzvimbo iyi uye haisangani neokisijeni. Kusagadzikana uku kweokisijeni kunoita kuti alumina ceramics iite basa rakakosha mundege, mauto nedzimwe nzvimbo.
Pamusoro pezvo, kugadzikana kwemakemikari kwealumina ceramics kunoratidzwawo mukudzivirira kwayo ngura neacid nealkali. Muhupenyu hwedu hwezuva nezuva, maacid nebases zvinhu zvakajairika, uye zvine mhedzisiro yekuora pazvinhu zvakawanda. Zvisinei, alumina ceramics inokwanisa kurwisa ngura neacid nealkali uye kuchengetedza hunhu hwayo hwepakutanga uye chimiro. Kuramba uku ngura neacid nealkali kunoita kuti alumina ceramics ishandiswe zvakanyanya mukugadzira chikafu, chemistry, medical nedzimwe nzvimbo.
Kazhinji, hunhu hwemakemikari hwezvigadziko zve alumina hwakagadzikana, kuitira kuti zvigone kuchengetedza kushanda zvakanaka uye chimiro chakanaka munzvimbo dzakasiyana-siyana dzakaoma. Kugadzikana uku kunoita kuti zvigadziko zve alumina zvishandiswe zvakanyanya muminda yakawanda.
