Alumina ceramic waa nooc ka mid ah alumina (Al2O3) oo ah walxaha dhoobada ugu weyn, oo loo isticmaalo filim qaro weyn oo isku dhafan.ceramics Alumina waxay leeyihiin conductivity wanaagsan, xoog farsamo iyo iska caabin heerkul sare.
Alumina ceramics hadda waxaa loo qaybiyaa laba nooc: nadiif sare iyo mid caadi ah.Nadiifinta sare ee alumina dhoobada waxay ka badan tahay 99.9% Al2O3 waxyaabaha dhoobada ah, sababtoo ah heerkulka sinnaanta ilaa 1650-1990 ℃, hirarka gudbinta ee 1 ~ 6μm, guud ahaan laga sameeyay galaas dhalaalid ah si loogu beddelo qulqulka platinum.Sababtoo ah gudbinta iftiinka iyo iska caabinta daxalka birta alkali, waxaa loo isticmaali karaa sida tuubada laambada sodium, warshadaha elektiroonigga ah ayaa sidoo kale loo isticmaali karaa sida guddiga isku-dhafka ah ee isku-dhafka ah iyo walxaha ilaalinta soo noqnoqda.
dhoobada alumina ee caadiga ah waxaa loo qaybiyaa 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain iyo noocyo kale marka loo eego nuxurka Al2O3, mararka qaarkood Al2O3 ee 80% ama 75% ayaa sidoo kale loo arkaa inay yihiin taxane dhoobo ah oo caadi ah.Waxaa ka mid ah, 99 alumina alaabta dhoobada ah ayaa loo isticmaalaa in lagu sameeyo heerkul sarreeya, tuubo foorno iyo qalab gaar ah oo u adkaysta, sida dhoobada dhoobada, shaabada dhoobada iyo valves biyaha, iwm. qaybo;85 maaddada dhoobada alumina ah ayaa inta badan lagu daraa qayb ka mid ah talc, hagaajinta sifooyinka korantada iyo xoogga farsamada, waxaana lagu xiri karaa molybdenum, niobium, tantalum iyo biraha kale, qaarkood ayaa sidoo kale loo isticmaalaa sida qalabka korontada.
