Telah dilakukan studi awal proses pemolingan dan karakterisasi sifat listrik terhadap bahan piezoelektrik ramah lingkungan BNT-BT-BKT. Dalam penelitian ini, sintesis bahan dilakukan dengan metode solid state reaction. Hasil analisis menunjukan bahwa Bahan BNT-BT-BKT memiliki struktur kristal perovskite rhombohedral yang bersifat hard ceramic. Bahan piezoelektrik 0,90BNT-0,05BT-0,05BKT memiliki konstanta dielektrik 1,29 x 102 dan temperatur Curie 428o C. Bahan piezoelektrik 0,93BNT-0,05BT-0,02BKT memilki konstanta dielektrik 1,87 x 102 dan temperatur Curie 428o C. Dari hasil poling 0,90BNT-0,05BT-0,05BKT didapatkan nilai frekuensi diri dan terlihat tegangan yang dihasilkan ketika dilakukan uji tekan terhadap bahan.Downloads
