The work entails the design and fabrication of a wet type ball milling machine to powder mill. The process of electricity production using solid oxide fuel cells (SOFC) relies on electrochemical oxidation of fuel and research is aimed at improving the performance of SOFC cathodes based on doping lanthanum cobaltate. This study involves adding zirconia (ZrO2 ) to a lanthanum cobalt oxide perovskite composite and then assessing its effect on the physical, mechanical, and electrical properties of a composite. In this paper, effect of sintering temperature is investigated by varying different wt.% of ZrO2 and MnO2 was changed according to the compound requirement for every sample prepared by the solid- state reaction. The final sintered samples were then undergone through characterization tests in terms of density, Diametral Tensile Strength (DTS) and compressive strength and so on. From the result, it is shown that composite with 5 wt.% of ZrO2 yields best result.
