This work has for objective to obtain vitrified ceramic tiles by adding nepheline-syenite flux and talc to a kaolinitic clay from Campos dos Goytacazes. Specimens were prepared by uniaxial pressure at 30 MPa followed by firing at 1100, 1150 and 1200oC. The fired specimens were submitted to the following tests: bulk density, linear shrinkage, three point bending mechanical strength and water absorption. The microstructure of the ceramic was evaluated by SEM. The results showed that the incorporation of nepheline-syenite and talc significantly enhanced the properties of the clay making it possible to attain the standard specification corresponding to vitrified ceramic tile.
