Popis: The ceramic sample of Ca1-xSrxTi1-yZryO3 where x = 0.5 and y = 0.5 (CSTZO) was synthesized by solid state reaction method. Analysis of X-ray diffraction data confirmed the formation of orthorhombic phase. The 2-D surface mo rphology was studied using scanning electron microscopy (SEM). The micrograph shows that the spherical shaped grains vary in the range of 1-2μm and the size of agglo merates varies in the range of 5 to 10 μm in diameter. The dielectric permittivity improved by the substitution of Sr and Zr on A and B-sites. Further, the dc conductivity measured by the two probe method in a temperature scan of 470K to 670K, showed NTCR of the material.
