Abstract：
The voids in α-Al₂O₃ irradiated by 85 MeV ¹⁹F ions of 5.28×10¹⁶cm^－2 have been observed during the post-annealing by a positron annihilation lifetime technique for the first time. The voids start to appear at 450℃. The void radius keeps nearly constant at ～0.29nm and the number of voids increases with increasing the annealing temperature from 550℃ to 750℃. Afterwards, the radius of voids increases rapidly with the annealing temperature and reaches 1.10nm at 1050℃.
