Tlhaloso ea Alumina ea Tafole e Sintered
Corundum ea tafole, e tsejoang hape e lealumina ea li-tafole tse sintered, ke mofuta o hloekileng haholo oa alumina (Al2O3) o sebetsoang ka ho khetheha ho ba lesebopeho se ikhethang sa tafole, kapa se bataletsengE hlahisoa ka ho sintering (ho futhumatsa ntle le ho qhibiliha) phofo ea alumina ea boemo bo holimo mochesong o ka holimo ho 1900°C, e leng se etsang hore likaroloana tsa alumina li hōle 'me li thehe likristale tse kholo, tse bataletseng, tse kang poleiti.
