Palavras-chave: titanato de cálcio, método rietveld


O objetivo do presente estudo é produzir titanato de cálcio (CT) com estrutura perovskita (ABO3) a partir do minério rutilo e carbonato de cálcio comercial. As matériasprimas foram caracterizados por fluorescência de raios-X e difração de raios-X (XRD). Diferentes composições foram formuladas, as amostras foram comprimidas a 150 MPa e sinterizadas em forno resistivo em temperaturas de 1300 ° C por 3h. As amostras foram analisadas através de XRD após o processo de sinterização e as fases foram quantificadas de acordo com o método Rietveld. As imagens foram obtidas por meio de microscopia eletrônica de varredura (MEV) a fim de mostrar as características das microestruturas formadas. De acordo com os resultados, a formação do CT depende da razão molar entre os cátions de cálcio e titânio nas composições.
