Synthesis and characterizations of structural, dielectric and optical properties of CCTO– PT composite
Gouitaa, N1, Lamcharfi, T2, Abdi, F3, Hadi, N4.
In this study, we have synthesized the (1-x) CaCu3Ti4O12 – (x) PbTiO3 (CCTO-PT) composites
with x = 0.00, 0.50 and 1.00 by using the solid-state method. We have then studied the structural, optical and dielectric properties of these composites. The X-ray diffraction diffractogram (XRD) showed that the ceramics at x = 0.00 and 1.00 (CCTO and PT) crystalize in a pure cubic and tetragonal phase respectively. Likewise, for CCTO-PT composite, we observed a coexistence of tetragonal and cubic phase in CCTO-PT composite composites. The scanning electron microscopy (SEM) micrographs showed homogeneous microstructure samples and consist of different grain shape. The large spherical grain structure is attributed to CCTO ceramic while the smaller grain form can be ascribed to the PT ceramic. The dielectric measurements results revealed an increase in dielectric permittivity value for CCTO-PT composite compared with pure CCTO and PT. The optical band gaps of the CCTO and PT are 2.50 and 3.00 eV, and increased to 3.50 eV for the CCTO/PT composite.
