Abstract

Barium zirconium titanate (BaZr_xTi_1-xO₃) with mole variations of zirconium (x) dopant at x = 0.01; x = 0.02; and x = 0.03 has been fabricated by solid state reaction method. Sintering temperature was done at temperature 1100⁰ C with holding time for 2h. Sample was characterized with XRD instrument and RLC meter to determine the effects of doping on the crystal structures and dielectric constant of BaZr_xTi_1-xO₃. The result of XRD analysis showed that BaZr_xTi_1-xO₃ has a tetragonal structure with a = b = c. Crystalline size of BaZr_xTi_1-xO₃ at x = 0.01; x = 0.02; and x = 0.03 are 34 nm, 33 nm, and 38 nm. RLC meter measurement obtained the dielectric constant are 331, 522, and 641, respectively.
