Abstract: Lead free Ba<subscript>0.85</subscript>Ca<subscript>0.15</subscript>Zr<subscript>0.1</subscript>Ti<subscript>0.9</subscript>O<subscript>3</subscript>(BCTZ) ceramic has been synthesized by sol-gel method. Properties of material are studied at different sintering temperatures for 5 hours. Structural and microstructural properties are analyzed by using X-ray diffractrometer (XRD) and scanning electron microscopy (SEM) at annealing temperature of 850°C and 1050°C XRD pattern confirm the perovskite structure of the material without any unwanted phases crystalinity increased with increase of sintering temperature so as roughness and porosity is decreased as shown by SEM micrographs. There is large improvement in density with rise of sintering temperature which also leads to drastic change in ferroelectric and dielectric properties. [ABSTRACT FROM AUTHOR]
