Abstract:
The characterization of BaTiO3 by using the method of experiment and comparison of 1: 1 is reported. This research uses chemicals with different concentrations i.e 0.005 mole, 0.006 mole 0.007 mole, and different temperatures i.e 600oC, 700oC, 800oC. The purpose of this research is to obtain the absorbance (spectrums) of BaTiO3 with temperature and concentration variations, then the characterization is done using UV-Vis spectroscopy method. The research results shows that at concentrations 0,005 mole, 0,006 mole, 0,007 mole before annealing of each having a wavelength 282,0 nm, 284,0 nm, 273,0 nm gives absorbance at 3,999 a.u, and at concentrations 0,005 mole, 0,006 mole, 0,007 mole after annealing at a temperature of 600 C, 700 C, 800 C, having a wavelength each 281,0 nm, 284,0 nm, 279,0 nm gives absorbansi 3,1503 a.u.
