Aluminium oxide inorganic substance ine kemikari formula A1203, musanganiswa wakaoma zvakanyanya uye unonyungudika we2054°C uye kuvira kwe2980°C.Iyo ionic crystal inogona kuvaionizedpakupisa kwepamusoro uye inowanzoshandiswa mukugadzirwa kwezvinhu zvinoramba.Calcined aluminium uye alumina zvose zvine chinhu chimwe chete, asi nekuda kweimwe nzira dzekugadzira uye mamwe maitiro akasiyana, kuitira kuti maviri mukushandiswa kwekuita uye saka pachava nemisiyano.
Alumina ndiyo main mineral yealuminium muzvisikwa, ichapwanyika uye kuisirwa nepamusoro tembiricha sodium hydroxide mhinduro kuwana sodium alumina mhinduro;sefa kuti ubvise zvakasara, tonhorera pasi iyo filtrate uye uwedzere aluminium hydroxide makristasi, mushure menguva yakareba ichikurudzira, iyo sodium alumina mhinduro inoora uye inonamira aluminium hydroxide;paradzanisa precipitate kunze uye kugeza, ipapo calcine pa 950-1200 ° C kuwana c-mhando alumina upfu, calcined Alumina ari c-mhando alumina.Kunyungudika nekubikira kwakakwira zvakanyanya.
Calcined alumina hainyunguriki mumvura uye asidhi, inozivikanwawo sealuminium oxide muindasitiri, uye ndiyo yakakosha zvinhu zvekugadzira simbi yealuminium;inogonawo kushandiswa mukugadzirwa kwezvidhinha zvakasiyana-siyana zvinoramba, refractory crucibles, refractory tubes uye yakakwirira tembiricha inodzivirira marabhoritari zviridzwa;inogonawo kushandiswa seyakasvibiswa, inopisa moto uye inozadza;kuchena kwepamusoro calcined alumina zvakare ndiyo mbishi yekugadzirwa kweartificial corundum, yekugadzira tsvuku tenzi dombo uye bhuruu tenzi dombo;inoshandiswawo kugadzirwa kwebhodhi substrates yemazuva ano makuru-akabatanidzwa maseketi.Calcined alumina uye alumina mukugadzira maitiro uye zvimwe zvinhu zviri mumusiyano mudiki, nzvimbo dzeindasitiri dzinoshanda dzakasiyanawo, saka mukutenga zvigadzirwa pamberi pekutanga kuwana nzvimbo dzekushandisa.
