1.High mechanical zog.Lub zog flexural ntawmalumina porcelain sintered khoomyog mus txog 250MPa, thiab cov khoom kub nias yog mus txog 500MPa.Lub purer lub alumina muaj pes tsawg leeg, lub zog ntau dua.Lub zog tuaj yeem khaws cia txog li 900 ° C ntawm qhov kub thiab txias.Siv lub zog mechanical ntawmalumina plooj (porcelain)., nws tuaj yeem ua rau cov khoom siv kho tshuab xws li porcelain.Mohs hardness ntawmalumina ceramicstuaj yeem ncav cuag 9, ntxiv rau nws muaj kev hnav zoo heev, yog li nws tau siv dav hauv kev tsim cov cuab yeej, pob li qub, sib tsoo lub log, cov ntsia hlau ceramic, bearings, thiab lwm yam, ntawm cov cuab yeej alumina ceramic thiab cov khoom siv li qub feem ntau siv.
2.High resistivity, zoo hluav taws xob rwb thaiv tsev kev ua tau zoo.Chav tsev kub resistivity ntawmalumina plooj (porcelain).yog 1015 Ω·cm, thiab lub zog rwb thaiv tsev yog 15kV / mm.Siv nws cov rwb thaiv tsev thiab lub zog, nws tuaj yeem ua rau hauv substrate, qhov (socket), lub txim hluav taws xob, lub plhaub hluav taws xob thiab lwm yam.
3.High hardness.Alumina porcelainmohs hardness ntawm 9, ntxiv rau zoo heev hnav tsis kam, yog li nws yog dav siv nyob rau hauv kev tsim cov cuab yeej, sib tsoo log, sib tsoo cov cuab yeej, kos duab tuag, extrusion tuag, bearings thiab hais txog.High precision tuaj yeem ua tiav ntawm kev txiav ceev thaum machining automotive engine thiab aircraft qhov chaw siv alumina ceramic cov cuab yeej.
4.High melting point.Kev tiv thaiv corrosion ntawm alumina porcelain yog 2050 ℃, thiab nws muaj kev tiv thaiv zoo rau Be, Sr, Ni, Al, V, Ta, Mn, Fe, Co thiab lwm yam hlau molten.Nws kuj tseem tiv taus NaOH yaig, iav thiab slag.Nws tsis cuam tshuam nrog Si, P, Sb thiab Bi hauv inert cua.Yog li ntawd, nws tuaj yeem siv los ua cov khoom siv refractory, rauv tube, iav hlau kos duab crucible, hollow pob, fiber ntau, thermocouple tiv thaiv npog, thiab lwm yam.
5. Zoo heev tshuaj stability.Ntau cov sulfides, phosphates, arsenides, chlorides, nitride, bromides, iodides, oxides, thiab sulfuric, hydrochloric, nitric, thiab hydrofluoric acids tsis cuam tshuam nrog alumina.Yog li ntawd, alumina tuaj yeem ua rau cov hlau ntshiab thiab ib qho siv lead ua loj hlob crucible, tib neeg cov pob qij txha, pob txha pob txha thiab lwm yam.
6. Optical zog.Alumina porcelaintuaj yeem ua rau cov khoom pob tshab (pob tshab alumina porcelain), sodium vapor teeb, microwave fairing, infrared qhov rais, laser oscillation caij, thiab lwm yam.
7.Lonic conductivity.Alumina porcelaintuaj yeem siv los ua cov khoom siv hnub ci cell thiab cov khoom siv roj teeb.
