The citrate gel was characterized by thermal analyses (TG and DTA), in order to determine the best polymerization temperature. The polymeric precursor is essentially amorphous and after calcination at 400 °C a mixture of tantalates, that are isomorphic to Bi3NbO7 and Bi5Nb3O15, starts to crystallize. At 600 °C, in addition to those phases, one could observe some peaks related to β-BiTaO4. Finally, at 800 °C β-BiTaO4 can be observed as a pure phase, with particle size estimated as 47 nm. The precursor polymeric method allowed obtaining β-BiTaO4 pure phase at temperatures significantly lower than those found for solid state reaction method.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-05-08T11:34:51Z No. of bitstreams: 1 __ac.els-cdn.com_S016757...ff0dfc82a8372c7d4c09fa4c552a7.pdf: 240472 bytes, checksum: 749db60a7d11deda9cb2581e9ee4830a (MD5)Made available in DSpace on 2012-05-08T11:34:51Z (GMT).
