This invention exposed the method of producing high performance cannular sapphire. It uses once-fashioning wetting EFG technology. It draws the cannular sapphire with required inner diameter and outer diameter and length from melt. Firstly, the size and specification of cannular sapphire need to be determined, then according to it to produce the matching cannular die. Then selecting sapphire particleboard from flame fusion method as raw material, and secelting the good seeding grew in (0001) direction by Czochralski method to grow cannular sapphire. The transverse temperature difference is within 2DEG C, the lognitudinal temperature grads within 10mm of die end face is 3-4DEG C, the growth speed is 30-40mm/h.
