Yiziphi izigaba ezintathu ezahlukene zokusinta ze-alumina ceramics? Ukusinta kuyinqubo eyinhloko yazo zonke i-alumina ceramics ekukhiqizeni, futhi kuzokwenzeka izinguquko eziningi ezahlukene ngaphambi nangemva kokusinta, i-Xiaobian elandelayo izogxila ezigabeni ezintathu ezahlukene zokusinta ze-alumina ceramics:
Okokuqala, ngaphambi kokushisa, ukulawulwa kwezinga lokushisa kulesi sigaba kubaluleke kakhulu, ngoba izinga lokushisa liyaqhubeka likhuphuka, umbungu uzoncipha, kodwa amandla nobuningi ngeke kushintshe kakhulu, uma kuncane kakhulu, okusanhlamvu ngeke kushintshe ngobukhulu, kodwa umbungu kulesi sigaba uthambekele kakhulu ekuqhekekeni, ikakhulukazi ngoba i-binder namanzi kukhishwe ngokuphelele, ngakho-ke kumelwe sinake ijubane lokwenyuka kwezinga lokushisa.
Okwesibili, enkambisweni yokusila, izinga lokushisa lizoshintsha ubukhulu obuncane, umzimba wombungu uyancipha kancane kancane, futhi ubuningi buzoshintsha kakhulu. Nakuba kungekho shintsho olucacile kokusanhlamvu okuncane kakhulu, zonke izinhlayiya azisekho eziboshiwe, futhi wonke ama-pores azoba mancane futhi abe mancane. Ngokufanayo, ngoba umzimba wombungu unoshintsho kuvolumu, ngakho-ke kusalula ukubonakala ukuguquguquka nokuqhekeka.
Okwesithathu, ekugcineni, ngemva kokusha, izinga lokushisa lizokhuphuka kakhulu, umzimba wombungu kanye nobuningi bazobhekana nezinguquko ezinkulu, ushintsho lokusanhlamvu ku-micro nalo lusobala kakhulu, ama-pores azoba mancane, ukwakheka kwama-pores amaningi ahlukanisiwe, kodwa kuzoba nama-pores athile asele ngqo ku-grain.
