Emkhakheni wesayensi yezinto zokwakha, sihlala sifuna izinto ezintsha ezinezakhiwo ezinhle kakhulu kanye nokuqina. Phakathi kwazo, izitsha zobumba ze-alumina zisetshenziswa kabanzi emikhakheni eyahlukene ngenxa yezakhiwo zazo ezinhle kakhulu zomzimba nezamakhemikhali, kanye nokumelana nokushisa okuphezulu kanye nokumelana nokugqwala. Namuhla, ake sibheke ngokujulile ukuzinza kwamakhemikhali kwezitsha zobumba ze-alumina.
Okokuqala, ukuzinza kwamakhemikhaliizitsha zobumba ze-aluminakubonakala kakhulu ekumelaneni kwayo nama-asidi amaningi, izisekelo nama-oxidants. Lokhu kungenxa yokuthi isakhiwo se-alumina ceramics siqinile futhi isibopho phakathi kwama-molecule siqinile, okwenza sikwazi ukugcina isimo saso sokuqala kanye nezakhiwo ezindaweni ezinzima kakhulu. Lokhu kuzinza kwenza i-alumina ceramics isetshenziswe kabanzi ezimbonini zamakhemikhali, uphethiloli, insimbi kanye neminye imboni.
Okwesibili, ukuzinza kwamakhemikhali kwe-alumina ceramics kubonakala nasezimpahleni zayo ze-antioxidant. Ngaphansi kwezimo zokushisa okuphezulu, izinto eziningi zizosabela nomoya-mpilo, okubangela ukuthi isakhiwo sazo kanye nezakhiwo zazo zishintshe. Nokho, i-alumina ceramics ihlala izinzile kule ndawo futhi ayisabela nomoya-mpilo. Lokhu kumelana ne-oxidation kwenza i-alumina ceramics idlale indima ebalulekile ezindizayo, kwezempi nakweminye imikhakha.
Ngaphezu kwalokho, ukuzinza kwamakhemikhali kwe-alumina ceramics kubonakala nasekumelaneni kwayo nokugqwala kwe-asidi ne-alkali. Empilweni yethu yansuku zonke, ama-asidi nezisekelo kuyizinto ezivamile, futhi zinemiphumela yokugqwala ezintweni eziningi. Kodwa-ke, i-alumina ceramics iyakwazi ukumelana nokugqwala kwe-asidi ne-alkali futhi igcine izakhiwo zayo zokuqala kanye nesakhiwo. Lokhu kumelana nokugqwala kwe-asidi ne-alkali kwenza i-alumina ceramics isetshenziswe kabanzi ekucubungulweni kokudla, ekhemistri, kwezokwelapha nakweminye imikhakha.
Ngokuvamile, izakhiwo zamakhemikhali ze-alumina ceramics zizinzile, ukuze zikwazi ukugcina ukusebenza okuhle kanye nesimo esihle ezindaweni ezahlukahlukene ezinzima. Lokhu kuzinza kwenza i-alumina ceramics isetshenziswe kabanzi emikhakheni eminingi.
