Abstract

Proses sintesis BNT-BT-BKT telah dilakukan dengan menggunakan metode solid state reaction. Sintesis BNT-BT dengan penambahan % mol BKT yaitu 2%, 5%, 8%, 15% juga mendapatkan struktur perovskite dengan komposisi yang optimal pada penambahan 5% mol BKT. Pola difraksi XRD pada bahan BNT-BT dengan penambahan % mol BKT menunjukkan adanya perubahan puncak-puncak yang tumpang tindih dari (200) rhombohedral menjadi (200) dan (002) dari tetragonal. Daerah perubahan fasa ini dikenal dengan MPB yang terjadi pada komposisi penambahan BKT 2%. Penambahan bahan dopan BKT ke BNT-BT menunjukkan perubahan pola difraksi sinar-x dengan pergeseran sudut 45° - 47°. Mikrograph SEM, menunjukkan penambahan 2% BKT pada BNT-BT memiliki bentuk partikel seperti jarum dengan panjang rata-rata 1,608 – 2,589 μm.
