Özet
This study deals with the effects of Ru–Bi partial substitutions on the thermal, structural and mechanical properties of Bi1.8−xRuxPb0.2Sr2CaCu2O10+δ (x = 0.0, 0.025, 0.050, 0.075) system, produced by using glass ceramics method. The effects of Ru–Bi partial substitutions on glass transition, nucleation and crystallization temperature were analyzed via differential thermal analyzer (DTA). Besides, microstructure and micromechanical properties of Ru–Bi partially substituted BSCCO glass ceramics were also investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Vickers microhardness measurements. From the DTA results, nucleation kinetics were studied by using Ozawa, Augis–Bennett, Takhor and Kissinger equations. In addition to this, activation energies and Avrami parameters were also calculated. According to the results of the thermogravimetric analyses, the amount of oxidation …
