In this work, we have especially focused on investigating the nano Boron doping effect into the Sm-Ca-Cu-O Ceramic [1,2]. The samples produced suitable with nominal composition selected as Sm1.75 Ca (2.20-x) B x Cu 3.4 O y (x = 0.0; 0.4, 0.8 and 1.0). This effect investigated through the TG/DTA, XRD, and SEM results. Lattice parameters (a, b, and c) got from the crystallographic knowledge, and they carefully calculated. The crystallographic growth seen because of the changing at the intensity of x-ray diffraction peaks. Increasing the Boron doping in the matrix have produced the crystal growth at especially SmBP and SmB10 samples, peaks intensity at 29° (220) Miller indices, has increased from 1.602 to 10.883, respectively. Namely, with increasing B-doping resulted in a transformation of the phase. In this way (at Boron free sample) it has achieved the orthorhombic phase transformation to the tetragonal phase created in the matrix.
