    PENGARUH SUHU ANNEALING TERHADAP MIKROSTRUKTUR BAHAN BARIUM TITANAT (BaTiO3) MENGGUNAKAN SCANNING ELECTRON MICROSCOPY (SEM)
    (2013-07-19) Zulpratama, D.; Krisman; Dewi, R.
    The samples material BaTiO3 with pellet shape have been made using experiment method of blending materials BaCO3 and TiO2 with the comparison of 1:1 as many as three samples. Each sample was annealed with the different temperature of 600, 700, and 800 C and then characterized using Scanning Electron Microscopy (SEM) in order to identify grain size and composition of the sample. The results of the characterization of SEM showed the physical form of microstructure BaTiO3 material that is shaped approaching dominant round with a different size and density. There are pores between grains of the particles, from measurement result EDX also obtained the composition of substances in samples. Material samples BaTiO3 which were annealed at the temperature of 600, 700, and 800 C have an average grain size of each is 94.34 nm, 108.7 nm, dan 131.58 nm respectively. It can be concluded that by increasing a high annealing temperature, BaTiO3 grain size will be larger.
