Barium strontium cobaltite (BSC) (Ba_0.5Sr_0.5CoO_3−δ) samples were successfully produced through modified chemical synthesis procedures. The methods used are hydrothermal, without water and surfactant (WOWS) sol-gel and co-precipitation technique. The effect of different synthesis procedures on structure, morphology and electrical conduction behaviour of BSC samples was studied. X-Ray diffraction showed the development of orthorhombic phase pure perovskite structure. FTIR spectroscopy confirmed the synthesis of perovskite structure by revealing its fingerprint peaks. Morphological studies by SEM displayed evenly dispersed, agglomerated and micro porous like morphology. Nyquist plots as a function of frequency displayed single semi-circular arcs. These arcs are an indication of grain boundary contribution in the electrical conduction mechanism. Modulus study displayed the Debye type conductivity relaxation. AC conductivity curves agreed well with Jonscher's power rule. Hydrothermally synthesized samples have the least impedances at higher frequencies. That form them possible candidate for cathode material in (IT-SOFCs) applications.

钴酸锶钡 (BSC) (Ba _0.5 Sr _0.5 CoO _3−δ) 样品是通过改进的化学合成程序成功生产的。使用的方法是水热法，无水和表面活性剂 (WOWS) 溶胶-凝胶和共沉淀技术。研究了不同合成程序对 BSC 样品的结构、形态和导电行为的影响。X 射线衍射显示正交相纯钙钛矿结构的发展。FTIR 光谱通过揭示其指纹峰证实了钙钛矿结构的合成。SEM 形态学研究显示出均匀分散、团聚和微孔状形态。作为频率函数的奈奎斯特图显示了单个半圆弧。这些弧是导电机制中晶界贡献的指示。模量研究显示了德拜型电导率弛豫。AC 电导率曲线与 Jonscher 的幂律非常吻合。水热合成样品在较高频率下阻抗最小。这使它们成为（IT-SOFC）应用中阴极材料的可能候选者。
