The technique includes of mixing, compacting and heating such as calcination &nbsp;and &nbsp;sintering. &nbsp;The &nbsp;three &nbsp;types &nbsp;of &nbsp;starting&nbsp; powders : CaCO3, CuO and TiO2&nbsp;were mixed then calcinated at 1100 &nbsp;and sintered for different temperatures at 500 , 700 &nbsp;and 900 . The sintered powders were characterized by X-ray diffraction (XRD) for investigate the cristalinity phase, &nbsp;FT-IR spectroscopy&nbsp; and &nbsp;grain &nbsp;size &nbsp;measurement. X-ray &nbsp;diffraction results&nbsp; &nbsp;show that CCTO synthesized with sintering treatment give material a better crystallinity than without using sintering treatment. FT-IR characteristic spectra show the main absorption at wavenumber 447,49 for 500 , 700 &nbsp;and 900 &nbsp;sintered powder that indicate the vibrations of <em>v</em>Ti-O-Ti type. Furthermore, the <em>v</em>Ti-O &nbsp;type vibrations&nbsp; &nbsp;appear at&nbsp; &nbsp;wavenumber 509,21 and 555,5 ; 516,92 and 570,93 ; 524,64 and 578,64 for &nbsp;500 , 700 &nbsp;and 900 &nbsp;sintered powder respectively. However, the results of grain size calculation point out that the grain size increases with increasing sintering temperature.</p> <p><strong>Keywords</strong>&nbsp;: <em>Solid-state reaction, X-ray diffraction, FT-IR spectroscopy.</em></p&gt;}, journal={PROSIDING SEMINAR NASIONAL FISIKA (E-JOURNAL)}, author={Febriana, Siska and Abraha, Kamsul}, year={2016}, month={Oct.}, pages={SNF2016-MPS } }
