In this work, the superconducting CuBa2LaCa2Cu4O11+δ compound was prepared by citrate precursor method and the electrical and structural properties were studied. The electrical resistivity has been measured using four probe test to find the critical temperature Tc(offset) and Tc(onset). It was found that Tc (offset) at zero resistivity has 101 K and Tc (onset) has 116 K. The X-ray diffraction (XRD) analysis exhibited that a prepared compound has a tetragonal structure. The crystal size and microscopic strain due to lattice deformation of CuBa2LaCa2Cu4O11+δ were estimated by four methods, namely Scherer(S), Halder-Wagner(H-W), size-strain plot (SSP) and Williamson-Hall, (W-H) methods. Results of crystal sizes obtained by these methods were compared with each other. In all these methods, the values of βhkl (full-width half-maximum (FWHM) for diffraction peaks) and miler indices (hkl) are determined from the results obtained from Fullprof, Mach, Origin and VESTA software. The lattice parameters a, b and c, lattice shape, d and degree of crystallization were calculated. It was found that the crystal size which are calculating by S, W-H, SSP and H-W were (174.8472, 171.1776, 173.1009 and 175.4386) A0 respectively while the lattice strain values were (none, 0.0025, 0.004 and 0.003464), respectively.
