Mataira esimbi esimbi eAlumina ceramic ane matiles matanhatuchinhu chakakosha chinoshandiswa zvakanyanya mukuchengetedza kupfeka kwemaindasitiri. Zvinogadzirwa nekupisa kwakanyanya kwealumina (Al₂O₃), kazhinji zvine huwandu hwealumina husingasviki 92%. Dhizaini yadzo ye hexagonal geometric inoita kuti pave nekukiya kwakasimba uye kufukidza kusina mipata pamusoro pe liner, zvichidzivirira kukwenya kwezvinhu uye kukanganiswa. Chigadzirwa ichi chinonyanya kushandiswa sejira rekudzivirira pazvikamu zvisina njodzi zvemidziyo yakasiyana-siyana yeindasitiri, zvichiwedzera hupenyu hwadzo hwebasa.
Mataira aya eceramic anozivikanwa nehunhu hwawo hwepanyama uye hwemakemikari. Nekuomarara kweMohs kwegiredhi 9, kuri pasi pedhaimani chete, anopa kudzivirira kupfekwa kwakanyanya. Kuwanda kwehuremu hwe3.6 g/cm³ kunoita kuti pave nekusimba kwakanyanya uye kudzivirira kukuvadzwa. Uyezve, ane coefficient yakaderera yekukweshana, kudzivirira ngura kwakanyanya, uye kusagadzikana kwemakemikari kwakasimba. Anoramba achishanda zvakanaka kana tembiricha yakakwira (nekupisa kunogara kuripo kusvika 1600°C) uye mamiriro ekushanda akaomarara pasina kukonzera kusvibiswa.
Mukushandiswa kwazvinoita, mataira esimbi esimbi ane hexagonal alumina anonamirwa pamusoro pevhu achishandisa manamira ane simba guru kana nzira dzemakanika. Kuaisa kunoshanda zvakanaka uye kugadzirisa kuri nyore. Anoshandiswa zvakanyanya mumasisitimu ekubata zvinhu mumaindasitiri akadai sesimba rekupisa, simbi, simende, migodhi, uye kugadzirisa makemikari—kusanganisira mapaipi, magokora, mahopper, mafeni, uye machute. Kugadzirwa kwawo kunoderedza nguva yekushanda kwemidziyo, kunoderedza mari yekugadzirisa, uye kunowedzera kuenderera mberi nekuvimbika kwemasisitimu ekugadzira.
Muchidimbu, mataira esimbi esimbi esimbi esimbi esimbi ealumina isimbi yakasimba uye inoshanda zvakanaka. Nekuoma kwayo, kugara kwenguva refu, uye kuchinjika kwakakura kwezvakatipoteredza, anopa mhinduro yehunyanzvi yakavimbika uye inodhura zvishoma yekuchengetedza michina yeindasitiri kubva mukusakara, zvichiita kuti ive chinhu chakakosha mumaindasitiri emazuva ano ekugadzira zvinhu.
