Strontium Titanate (SrTiO 3 ) is one attractive material studied. In this study, SrTiO 3 has been fabricated via the co-precipitation technique. The samples were sintered at 800°C and 900°C with holding times of 2 h and 4 h for each temperature. The purposes of this study were to synthesize SrTiO 3 material using co-precipitation technique and to observe the microstructure and chemical bonds of the SrTiO 3 as the variations of the sintering temperatures and holding times. According to the X-Ray Diffraction (XRD) results, the sintering temperatures and holding times influenced the intensity values and peak broadening. The alteration in both parameters consequently changed the crystallite size and lattice strain of the SrTiO 3 material. Furthermore, the Fourier Transform Infrared (FTIR) results validated the SrTiO 3 material by existence of Sr-Ti-O chemical bonds. Also, the absorption peaks of O-H, C-H, and C=O chemical bonds in the SrTiO 3 declined due to the higher temperature and longer holding time demonstrating impurities declined. Therefore, according to this study, the sintering temperature of 900°C and the holding time of 4 h was the best parameter for fabricating SrTiO 3 powder.
