Aluminium oxide chinhu chichena kana zvishoma chitsvuku chakaita setsvimbo ine density ye 3.5-3.9g/cm3, inonyungudika inosvika 2045, uye panovira inosvika 2980 ℃. Hainyungudike mumvura asi inonyungudika zvishoma mualkali kana asidhi. Kune mhando mbiri dzemahydrates: monohydrate uye trihydrate, imwe neimwe ine a uye y akasiyana. Kupisa mahydrates pa200-600 ℃ kunogona kuburitsa alumina yakashongedzwa nemhando dzakasiyana dzekristaro. Mumashandisirwo anoshanda, Y-mhando activated alumina inonyanya kushandiswa. Kuoma (Hr) yealuminium ndeye 2700-3000, iyo Young's modulus 350-410 GPa, iyo inopisa conductivity ndeye 0.75-1.35 / (m * h. ℃), uye mutsara wekuwedzera coefficient i8.5X10-6 ℃ -1 (tembiricha yekamuri -1000 ℃). Yakanyanya kuchena ultrafine alumina ine zvakanakira kuchena kwepamusoro, diki diki saizi, yakakwira density, yakakwira tembiricha simba, corrosion resistance, uye nyore sintering. Yakakwirira kuchena ultrafine alumina ine hunhu hwakadai seyakanaka uye yunifomu yehurongwa dhizaini, chaiyo yezviyo muganho chimiro, yakakwira tembiricha kugadzikana, kuita kwakanaka kwekugadzirisa, kupisa kupisa, uye kugona kusanganisa nezvinhu zvakasiyana.
Kushandiswa kwepamusoro-kuchena alumina
Yakakwirira kuchena alumina ine hunhu hwekupokana necorrosion, kupisa kwekushisa kwepamusoro, kuomarara kwepamusoro, kusimba kwepamusoro, kupfeka kusagadzikana, oxidation kuramba, uye yakanaka insulation ine nzvimbo yakakura yepasi. Inoshandiswa zvakanyanya munzvimbo dzepamusoro-tekinoroji dzakadai sebioceramics, yakanaka ceramics, makemikari anokonzeresa, isingawanzo pasi matatu mavara gene fluorescent poda, akasanganiswa edunhu machipisi, aerospace light source zvishandiso, humidity sensitive sensors, uye infrared absorption zvinhu.
