Examine the Impact on the Electrical and Structural Properties of Superconducting Compounds of Partial Substitution of Ag for Ba

Abstract

We manufactured the compound (Bi_1.8(Pb_0.2)Ba_2-xAg_xCa₂Cu₃O_10+δ) for this research. based on bismuth and evaluated the impact of substituting silver oxide (AgO) for barium oxide (BaO) at concentrations of x = (0.0,0.05,0.1,0.15,0.2, and 0.25 The samples were made using the state solid reaction method. After being consolidated for 26 hours at the sintering temperature of 720°C and a heating rate of 10°C per minute, the samples were cooled to room temperature at the same heating rate. The critical temperature has been determined using the four-probe technique, and the resistivity as a function of temperature test shows that every specimen behaves metallically. When x=0.05, the maximum critical temperature we have discovered is 124.2k. The surfaces of these systems were also inspected using atomic force microscopy, or AFM. It was used to compute the root mean square (Rg), average roughness (Ra), and average diameter (nm). According to the findings, the sample with the lowest average diameter (131.5)was the one with the replacement ratio (0.2).
