Abstract


Telah dilakukan pembuatan sampel dari bahan Barium Strontium Titanat (BST) dengan komposisi Ba0,3Sr0,7Tio3 dengan  menggunakan metode sol gel dan di annealing  pada suhu 600oC,650oC dan 700oC.  Ukuran butira dan  ketebalan sampel dikarakterisasi menggunakan Field Emission Scanning Microscopy (FESEM). Ukuran butiran meningkat dengan meningkatnya suhu annealing. Nilai rata-rata ukuran butiran dari temperatur 600oC, 650oC dan 700oC adalah : 21,20 nm; 22,30 nm dan 26.8 nm. Nilai ketebalan sampel masing-masing adalah 31,28 nm;37,5nm dan 39,08nm.   

Keywords
