Özet

In this work, we have especially focused on investigating the nano Boron doping effect into the SmCa-Cu-O Ceramic [1,2 ]. The samples produced suitable with nominal composition selected as Sm1.75Ca(2.20-x)BxCu3.4Oy (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 degrees (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. (C) 2021 Elsevier B.V. All rights reserved.
