1.High mechanical simba.The flexural simba realumina porcelain sintered zvigadzirwainosvika 250MPa, uye iyo yezvigadzirwa zvinodzvanywa zvinosvika ku500MPa.Iyo yakachena iyo alumina yakagadzirwa, inowedzera simba.Simba rinogona kuchengetedzwa kusvika 900 ° C pakupisa kwepamusoro.Kushandisa simba remagetsi realumina porcelain, inogona kugadzirwa kuita ma mechanical parts se porcelain.Iyo mohs kuoma kwealumina ceramicsinogona kusvika 9, uye ine yakanakisa kupfeka kuramba, saka inoshandiswa zvakanyanya mukugadzira maturusi, mavharuvhu ebhora, mavhiri ekukuya, zvipikiri zveceramic, mabearings, nezvimwewo, pakati peiyo alumina ceramic maturusi uye mavharuvhu eindasitiri ndiwo anonyanya kushandiswa.
2.High resistivity, yakanaka magetsi ekudzivirira kushanda.Iyo tembiricha yekamuri resistivity yealumina porcelainiri 1015 Ω · cm, uye simba rekudzivirira i15kV/mm.Uchishandisa kuvharirwa kwayo uye simba, inogona kugadzirwa kuita substrate, socket, spark plug, redunhu shell uye zvichingodaro.
3.Kuoma kwepamusoro.Alumina porcelainmohs kuoma kwe9, pamwe nekunyanya kupfeka kusagadzikana, saka inoshandiswa zvakanyanya mukugadzira maturusi, mavhiri ekukuya, maturusi ekukuya, kudhirowa kufa, extrusion kufa, mabheji uye zvichingodaro.Kunyatsoita kwepamusoro kunogona kuwanikwa nekumhanya kwekucheka kwakanyanya paunenge uchigadzira injini yemotokari uye zvikamu zvendege uchishandisa alumina ceramic maturusi.
4.High melting point.Kudzivirirwa kwekuora kwealumina porcelain ndeye 2050 ℃, uye ine kuramba kwakanaka kuBe, Sr, Ni, Al, V, Ta, Mn, Fe, Co nedzimwe simbi dzakanyungudutswa.Iyo zvakare inopikisa zvakanyanya kukukurwa kweNaOH, girazi uye slag.Iyo haidyidzane neSi, P, Sb uye Bi mumhepo inert.Naizvozvo, inogona kushandiswa senge refractory zvinhu, choto chubhu, girazi waya yekudhirowa crucible, hollow bhora, fiber, thermocouple inodzivirira chivharo, nezvimwe.
5. Yakanakisa kugadzikana kwemakemikari.Mazhinji sulfides akaoma, phosphates, arsenides, chlorides, nitride, bromides, iodides, oxides, uye sulfuric, hydrochloric, nitric, uye hydrofluoric acids hazvidyidzani nealuminium.Naizvozvo, alumina inogona kugadzirwa kuita simbi yakachena uye imwechete kristaro kukura crucible, majoini evanhu, mapfupa ekugadzira uye zvichingodaro.
6. Optical properties.Alumina porcelaininogona kugadzirwa kuita yakajeka zvinhu (transparent alumina porcelain), sodium vapor rambi, microwave fairing, infrared hwindo, laser oscillation element, nezvimwe.
7.Lonic conductivity.Alumina porcelaininogona kushandiswa se solar cell material uye bhatiri zvinhu.
