Amabhlogo e-alumina ceramic angagugiZenziwe ngokunemba kusuka ku-aluminium oxide emsulwa kakhulu (okuqukethwe kwe-Al₂O₃ ≥ 92–99%) ngokucindezela okomile kanye nokushisa okuphezulu ku-1,500–1,700°C. Le nqubo yokukhiqiza ethuthukisiwe ikhiqiza izinto zobumba ezinobunzima obungavamile—ezilinganisa u-9 esikalini se-Mohs kanye ne-HRA 80–90 esikalini se-Rockwell, okwesibili kuphela ngemva kwedayimane. Ngobuningi bevolumu obungu-3.60–3.85 g/cm³, la mabhulokhi anesisindo esingaba yisigamu sensimbi, okunciphisa kakhulu umthwalo wemishini ngenkathi enikeza ukuvikelwa okuphezulu kokuguguleka. Izinto zibonisa ukumuncwa kwamanzi okuphansi kakhulu ngaphansi kuka-0.01%, okuqinisekisa ukusebenza okuzinzile ngisho nasezindaweni ezinomswakama.
Ukumelana okuphezulu kokuguguleka kwamabhulokhi e-alumina ceramic kuholela ngqo empilweni yesevisi yemishini ende kanye nezindleko zokulungisa ezincishisiwe. Ukuhlolwa okuzimele kubonisa ukuthi ukumelana kwawo nokuguguleka cishe kuphindwe izikhathi ezingu-260-266 kunensimbi ye-manganese kanye nezikhathi ezingu-170-171.5 kunensimbi ephezulu ye-chromium. Njengoba amandla okucindezela afinyelela ku-≥2,000 MPa kanye namandla okuguquguquka angu-255-300 MPa, lawa mabhulokhi amelana nemithwalo enzima ngaphandle kokuqhekeka. Ukuqina kwawo kokuqhekeka (i-KIC) okungu-≥4.8 MPa·m¹/² kuqinisekisa ukuqina ngaphansi kwezimo zokucindezeleka ezijikelezayo. Lezi zici zokusebenza zenza amabhulokhi e-alumina ceramic abe yisisombululo esifanele se-lining sezinhlelo zokusebenza eziguguleka kakhulu njenge-chutes, ama-hopper, ama-cyclone, kanye nezinhlelo zokuphatha izinto.
Kusukela ekuvubukuleni nasekucubungulweni kwamaminerali kuya ekukhiqizweni kukasimende, ekwenzeni insimbi, ekukhiqizeni amandla okushisa, nasekucubungulweni kwamakhemikhali, amabhlogo e-alumina ceramic angagugi abonakalise inani lawo kuzo zonke izimboni lapho ukuguguleka kwemishini kuyinkinga eyinhloko. Atholakala kumazinga okuhlanzeka kwe-Al₂O₃ angu-92%, 95%, kanye no-99%, lawa mabhlogo angenziwa ngokwezifiso ukuze ahlangabezane nezidingo ezithile zohlelo lokusebenza, ngokuhlanzeka okuphezulu okuletha ukumelana nokuguguleka okuthuthukisiwe. Ngokufaka amabhlogo e-alumina ceramic ezindaweni ezibucayi zokuguguleka, abaqhubi bezitshalo banganciphisa kakhulu isikhathi sokungasebenzi esingahleliwe, banciphise ukufakwa kwezingxenye esikhundleni, futhi bafinyelele izindleko eziphansi zobunikazi phakathi nomjikelezo wokuphila kwemishini.
