Resumo: A Brazilian (from Paraná State) kaolin was pretreated by using a thermal activation process and further, utilized in the synthesis of a zeolite. The natural and pretreated samples were characterized on the basis of Atomic Absorption and Infrared (IR) spectroscopic data, X-Ray Diffraction (XRD) and textural analysis by N2 adsorption. The IR and XRD data of samples submitted to thermal treatment at 1073K showed destruction, suggesting its transformation into metakaolin. The destruction of kaolin structure turns the present atoms of Si and Al more accessible and appropriated for the use in zeolite synthesis. An A zeolite with 66% of crystalline character was synthesized from the kaolin pretreated.

O pré-tratamento consiste em uma ativação térmica do caulim. As amostras naturais e pré-tratadas foram analisadas por espectroscopia de Absorção Atômica e de Infravermelho, difração de raios-X (DRX) e Análise Textural por adsorção de N2. Foi observada a transformação do caulim em metacaulim com o tratamento térmico a 1073K. Tanto o espectro de infravermelho quanto o difratograma de raios-X denotaram a destruição da estrutura do caulim e a sua transformação para metacaulim. A desestruturação do caulim com que os átomos de Si e Al presentes fiquem mais acessíveis, tornando-o mais apropriado para a síntese de zeólita, na qual esses elementos são utilizados para formar sua estrutura. A partir do caulim paranaense pré-tratado termicamente, foi possível sintetizar zeólita A com 66% de cristalinidade.Universidade Estadual De Maringá2008-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/224110.4025/actascitechnol.v25i1.2241Acta Scientiarum.
