The thin film of BZT is characterized by using X-Ray Diffraction (XRD). The result samples in temperature 600⁰C dan 650⁰C to know crystal structure and size particle using Scherrer formula. The crystalize size of the sample is affected by the annealing. Moreover, the X-Ray Diffraction results show that the crystal structure of the sample is tetragonal, that has a lattice parameters of a = b = 4,03 Å c = 4,08 .enBaZr01Ti0,9O3Sol-Gel MethodAnnealingCrystal StructureArticle
