Avaliação das propriedades físico-mecânicas de uma massa cerâmica para revestimento poroso (BIII) Evaluation of physical-mechanical properties of a ceramic paste for porous wall tile (BIII)

Abstract

O presente trabalho teve por objetivo estudar as propriedades físico-mecânicas de uma massa para revestimento cerâmico poroso base vermelha a partir de matérias-primas da região Norte Fluminense. A massa cerâmica preparada pelo processo via seca foi caracterizada quanto a composição química, análise de tamanho de partícula, difração de raios X e comportamento térmico. Os corpos cerâmicos foram prensados sob 35 MPa e sinterizados entre 1080 e 1200 ºC usando um ciclo de queima rápido. A microestrutura sinterizada foi avaliada por microscopia eletrônica de varredura. Os corpos cerâmicos sinterizados exibiram baixos valores de retração linear, resultando em boa estabilidade dimensional. A microestrutura é caracterizada por alta porosidade. Além disso, foram atingidas as especificações para revestimento poroso (NBR 13818) em termos da tensão de ruptura à flexão e da absorção de água dos corpos cerâmicos sinterizados, indicando o potencial das matérias-primas cerâmicas do Norte Fluminense para este tipo de aplicação.The present work aimed at studying the physical-mechanical properties of a ceramic paste for red porous wall tile using raw materials from the Northern Fluminense region. The ceramic paste was prepared by dry process and characterized regarding chemical composition, particle size analysis, X-ray diffraction and thermal behavior. The ceramic bodies were pressed under 35 MPa and sintered from 1080 to 1200 ºC in a fast-firing cycle. The sintered microstructure was evaluated by scanning electron microscopy. The results showed that the sintered ceramic bodies exhibited low values of linear shrinkage, resulting in good dimensional stability. The microstructure was characterized by high porosity. In addition, the specifications for porous wall tiles (NBR 13818) were achieved in terms of the flexural strength and water absorption of the sintered ceramic bodies, indicating the potential of the ceramic raw materials of the region for this application.
