## Abstract The possibibity of the existence of cleavage in Ξ±βAl~2~O~3~ single crystals has been estimated by elementary structural considerations and has been shown that the {101} and {1120} planes are the more probable cleavage planes. The values of the fracture surface energy measured by Wiederh
