Uniform thermal field with the axial temperature gradient of 11.6 K/cm was formed in a cylindrical heater. There were obtained 15x85x300 mm3 sapphire ribbons with dislocation density up to 103 cm-2. The dislocation density of sapphire ribbons at the axial temperature gradient of 11.6 K/cm was found...
