Abstract:

A novel technique for annealing corundum crystals consists in rapidly cooling the crystals to room temperature after growth is complete, transferring them to an automatically programmed electric furnace and reheating them to 1980 deg. C, and then cooling them at the same rate as they were brought up to the annealing temperature. The total cycle is 32 hr. Results are consistently reproducible. Author
