Abstract: CaRuO3–CaTiO3 ceramic composites were prepared by sintering for short times for potential applications in the areas of electronic ceramics. Scanning electron microscopy and energy dispersive X-ray analysis showed two separate phases, CaRuO3 and CaTiO3 in the composite. Conductivity data, measured by the four-probe method, showed that the composites have high electrical conductivity when x ≥0.19 in xCaRuO3–(1− x)CaTiO3 composites. Furthermore, the nanoparticle of calcium ruthenate prepared by reverse micelle synthesis was used to be conductive agent for the composite. The result shows that the use of nano-sized calcium ruthenate enabled higher electrical conductivity to be maintained down to x =0.09. [Copyright &y& Elsevier]
