Abstrak
It has been conducted a research about the replacement of Gd with La on the phase of GBCO-123: Gd1-xLaxBa2Cu3O7-? (x = 0.0 to 0.5), partially. The compound is called as GLBCO-123 phase. The research aimed is to obtain information about the effects of substitution Gd with La in the Synthesis of GLBCO-123 phase and its particle size. Samples were synthesized by using wet mixing method. The materials used are Gd2O2, La2O2, BaO, CuO and nitric acid as a solvent. The characterizations were conducted by XRD and SEM-EDXA. The result showed that the GLBCO-123 phase which contain La<0.25 is in the form of nanoparticle with size of about 96 nm. The volume fraction is decreased with increasing the content of La.
