Dislocation structure of {112̄0}/〈11̄00〉 2° tilt grain boundary in alumina was observed by transmission electron microscopy (TEM). The grain boundary consisted of periodical array of basal dislocations, which were dissociated into pairs of 1/3〈101̄0〉 and 1/3〈011̄0〉 partials with {112̄0} stacking-fault in between. The relationship between the separation distance of partials and the stacking-fault was modeled by considering the force balances of periodical dislocations. The estimated stacking-fault energy for 2° tilt grain boundary was consistent with the previous reports.
