Fused corundum zvidhinha zvegirazi rinonyungudika chiravira

Iyo yakasanganiswa chena corundum zvidhinha i α-AL2O3, iri ye trigonal crystal system. Iyo inowanikwa nekunyungudutsa maindasitiri alumina pakakwirira tembiricha mune yemagetsi arc tira, kutonhora uye crystallization kuita ingots, uyezve nekupwanya, kusarudza, kugadzirisa uye kuongorora. Iyo yakagadzikana imwe pakati pezvakawanda zvakasiyana alumina. Iyo ine yakakwira utsotso nzvimbo (2030), yakakwira density (3.99 ~ 4.0g / cm3), compact chimiro, yakanaka yekupisa conductivity, diki yekupisa yekuwedzera coefficient (86 × 10-7 /) uye yunifomu. Iyo amphoteric oxide, kazhinji isina kusimba alkaline kana kwazvakarerekera pakakwirira tembiricha, uye ine yakanaka makemikari kugadzikana. Naizvozvo, yakasanganiswa chena corundum ndeyezvinhu zvinochinja zvekukanda mari. Yakasanganiswa chena corundum zvinhu zvakapfuma mune zvicherwa zviwanikwa uye zvakaderera mumutengo, izvo zvakakodzera kusarudzwa nekusimudzira.
