Effect of B2O3 addition on the formation and properties of Tl-2212 and Tl-2223 superconductors

We have studied the effect of B2O3 addition on the formation and properties of the Tl‐based superconductors. Polycrystalline Tl‐2212 and Tl‐2223 samples were synthesized by adding B2O3 to the chemicals at the first and at the second stage of two stages sintering processes (3+1 h) at 860 °C. X‐ray po...
