Synthesis and Characterization of a Perovskite Barium Zirconate (BaZrO[subscript 3]): An Experiment for an Advanced Inorganic Chemistry Laboratory

Journal of Chemical Education, v93 n6 p1120-1123 Jun 2016
In this experiment, the students explore the synthesis of a crystalline solid-state material, barium zirconate (BaZrO3) by two different synthetic methods: (a) the wet chemical method using BaCl[subscript 2]·2H[subscript 2]O and ZrOCl[subscript 2]·8H[subscript 2]O as the precursors, and (b) the solid-state reaction from BaCO[subscript 3] and ZrO[subscript 2]. BaZrO[subscript 3] adopts a perovskite structure with a cubic unit cell. The intermediate and the products are examined by various characterization techniques. The identity and the purity of the products are determined by powder X-ray diffraction technique. The structural information on the products is analyzed by the XRD patterns, where students apply the sin[superscript 2]?-ratio method to determine the type and dimension of the unit cell. The composition of the Ba[superscript 2+] and Zr[superscript 4+] ions in the product is determined by the gravimetric analysis, while the vibrational modes of the product are observed by Infrared Spectroscopy.
