| Abstract: | High quality large sapphire tubes were successfully formed via self-designed crystal-growth equipment using Edge-defined Film-fed Growth(EFG)Method.The inner/outer diameters of the tubes were 31/58 mm and 50/65 mm respectively,and the length of the tube exceeded 300 mm.No crack,polycrystalline structure or visible bubble was observed in the tube. |
