Alumina ceramic yog ib hom alumina (Al2O3) ua cov khoom siv ceramic, siv hauv cov yeeb yaj kiab tuab sib xyaw ua ke.Alumina ceramics muaj zoo conductivity, txhua yam muaj zog thiab kub tsis kam.
Alumina ceramics tam sim no muab faib ua ob hom: siab purity thiab ntau.High purity alumina ceramic yog ntau tshaj 99.9% Al2O3 cov ntsiab lus ntawm cov ntaub ntawv ceramic, vim nws sintering kub txog 1650-1990 ℃, kis wavelength ntawm 1 ~ 6μm, feem ntau yog ua los ntawm molten iav los hloov lub platinum crucible.Vim nws lub teeb xa hluav taws xob thiab tsis kam mus rau alkali hlau corrosion, nws tuaj yeem siv los ua sodium teeb raj, hauv kev lag luam hluav taws xob kuj tseem tuaj yeem siv los ua pawg thawj coj saib kev sib txuas thiab cov khoom siv hluav taws xob ntau zaus.
Ordinary alumina ceramics tau muab faib ua 99 plooj (porcelain), 95 plooj (porcelain), 90 plooj (porcelain), 85 plooj (porcelain), 85 plooj (porcelain) thiab lwm yam ntau yam raws li Al2O3 cov ntsiab lus, qee zaum Al2O3 cov ntsiab lus hauv 80% lossis 75% kuj suav tias yog alumina ceramic series.Ntawm lawv, 99 alumina ceramic cov ntaub ntawv yog siv los ua kom kub kub crucible, rauv tube thiab cov ntaub ntawv tshwj xeeb hnav-resistant, xws li ceramic bearings, ceramic seals thiab dej li qub, thiab lwm yam. 95 alumina ceramic khoom yog siv los ua corrosion resistant, hnav resistant. qhov chaw;85 alumina ceramic khoom yog feem ntau tov nrog ib feem ntawm talc, txhim kho cov khoom siv hluav taws xob thiab cov khoom siv dag zog, thiab tuaj yeem muab khi nrog molybdenum, niobium, tantalum thiab lwm yam hlau, qee qhov kuj siv los ua hluav taws xob lub tshuab nqus tsev.
