Pembuatan Ba0,8Sr0,2TiO3 menggunakan Metode Co-precipitation dengan Variasi Suhu Sintering

Abstract

Ba 0,8 Sr 0,2 TiO 3 was made by co-precipitation method with the sintering temperature of 600 o C, 700 o C, 800 o C and 900 o C for 4 hours. Sintering temperature was varied to investigate its effect on microstructure and dielectric constant of Ba 0,8 Sr 0,2 TiO 3. microstructure characterization was performed by X-Ray Diffraction (XRD) instrument. Dielectric constant characterization was perform by LCR meter. The crystal size increased significantly with increasing sintering temperature. Measurements of dielectric constant were performed at range of frequency 0.01 to 100 KHz. Dielectric constant value is highest at the lowest frequency. Dielectric constant value size increased significantly with increasing sintering temperature.
