High alumina ceramic raj yog ib qho zoo tshaj plaws inorganic tsis yog -cov khoom siv hlau tubular, txawv los ntawm nws cov ntsiab lus alumina siab - nrog Al₂O₃ cov ntsiab lus tsis tsawg dua 95%, thiab siab -kawg variants ncav cuag tshaj 99%, ib qho tseem ceeb specification uas teev nws sib nrug los ntawm tej yam ntuj tso tej hub raj. Nws cov txheej txheem tsim ua raws li cov qauv kev sib xyaw ua ke ntawm cov hmoov metallurgy: siab -purity alumina hmoov yog zoo li tus los ntawm precision txoj kev xws li txias isostatic nias, plam casting, los yog qhuav nias los tsim ib lub cev ntsuab, uas yog ces sintered ntawm 1600℃~ 1800℃kom tiav densification. Cov txheej txheem sintering no ua kom muaj qhov tseem ceeb ntawm -Al₂O₃ (corundum) siv lead ua qauv, lub hauv paus rau cov khoom siv tshwj xeeb.
Raws li tau teev tseg hauv nws cov kev tsis sib xws, siab alumina ceramic raj sib xyaw ua ke ntawm qhov sib xyaw ua ke thiab kev tiv thaiv corrosion ntawm cov ntaub ntawv ceramic nrog siab - qhov kub thiab txias uas cov hlau tsis tuaj yeem sib tw - muaj peev xwm tiv taus ntev - lub sij hawm ua haujlwm kub txog li 1600℃yam tsis muaj softening los yog deforming, thiab tiv taus erosion (feem ntau yog acidic). hydrofluoric acid thiab concentrated alkalis).
Tsis zoo li cov raj ceramic zoo tib yam nrog cov ntsiab lus alumina qis dua, cov khoom lag luam muaj cov khoom siv zog ntau dua (nrog lub zog compressive tshaj 300 MPa) thiab hnav tsis kam, ua kom lub neej ua haujlwm ntev dua 2-3 zaug. Rau kev lag luam kev lag luam ua haujlwm nyob rau hauv ib puag ncig hnyav, siab alumina ceramic raj txo qhov zaus ntawm cov khoom siv hloov thiab txij nkawm downtime, thaum nws cov kev ua haujlwm ruaj khov ua kom zoo ib yam. Txawm tias nyob rau hauv siab -kub, corrosive, los yog siab - coj scenarios, cov khoom muab kev ntseeg siab, ntev kev ua tau zoo uas txhawb kev ua tau zoo thiab kev nyab xeeb ntawm kev lag luam.
