Description
CaCu$_3$Ti$_4$O$_1$$_2$ powders were synthesized by modified Sol-gel method with Hydrothermal using Ca(NO$_3$)$_2$• 4H$_2$O, Cu(NO$_3$)$_2$• 3H$_2$O, Ti(OC$_3$H$_7$)$_4$ and freshly extracted egg white (ovalbumin) in aqueous medium. The precursor was calcined at 800, 900 and 1000 °C in air for 8 h to obtain nanocrystalline powders of CaCu$_3$Ti$_4$O$_1$$_2$. The calcined CaCu$_3$Ti$_4$O$_1$$_2$ powders were characterized by XRD, TEM, and EDX. The XRD results indicated that all calcined samples have a typical perovskite CaCu$_3$Ti$_4$O$_1$$_2$ structure and a small amount of CaTiO$_3$, CuO and TiO$_2$. TEM micrographs showed particle size 100 – 500 nm and EDX results showed elements of CaCu$_3$Ti$_4$O$_1$$_2$ powders have calcium, copper, titanium and oxygen.
