Abstract: Increasing technology has lead to proliferating electronic equipments. One component of electronic equipment is capacitor, which can be made of barium titanate (BaTiO3). This study aims to synthesize and to characterize BaTiO3 from a mixture of BaCl2 and TiCl4 by observing changes in temperature and the stage of the reaction. This study was carried out in several stages, i.e synthesis of BaTiO3 by hydrothermal method, changes in the reaction steps, changes in pH, compared the results by nonhydrothermal method and characterization by X-ray diffraction (XRD). Based on XRD results, synthesis of BaTiO3, using the method of hydrothermal (T = 120-150 °C), changes in the reaction steps, also in pH, had not been able to produced pure BaTiO3. It can be seen from low intensity of BaTiO3 and presence of other impurities in the form of TiO2 as can be found in all methods including non-hydrothermal method (T = 600 °C).
Seiring dengan kemajuan teknologi saat ini, peralatan elektronik semakin berkembang. Salah satu komponen penyusun peralatan elektronik adalah kapasitor. Salah satu bahan penyusun kapasitor, ialah barium titanat (BaTiO3). Penelitian ini bertujuan mensintesis dan mencirikan BaTiO3 dari campuran BaCl2 dan TiCl4 dengan mengamati perubahan suhu dan tahapan reaksi. Penelitian ini meliputi beberapa tahap, yaitu sintesis BaTiO3 dengan metode hidrotermal, perubahan tahapan reaksi, perubahan pH, dan membandingkan hasil sintesis menggunakan metode nonhidrotermal, serta pencirian dengan difraksi sinar-X (XRD). Berdasarkan hasil XRD, sintesis BaTiO3 menggunakan metode hidrotermal (T = 120-150 oC), perubahan tahapan reaksi, dan perubahan pH belum bisa menghasilkan BaTiO3 murni. Hal ini dapat dilihat dari rendahnya intensitas BaTiO3 yang terbentuk serta masih terdapatnya pengotor lain berupa TiO2, seperti pada metode nonhidrotermal (T = 600 oC).
