%X this work had for objective to development vitrified ceramic tiles body using the nepheline-syenite flux with a kaolinitic clay. formulations were prepared with addition of 0, 30 and 50 wt.% of nepheline-syenite to the clay. specimens were prepared by uniaxial pressure at 30 mpa followed by firing at 1100, 1150 and 1200 oc. the evaluated physical and mechanical properties were: dry bulk density, linear shrinkage, three point bending mechanical strength and water absorption. the microstructure of the fired ceramics was evaluated by scanning electron microscopy and x-ray diffraction. the results showed that the incorporation of nepheline-syenite significantly enhanced the properties of the clay making it possible to reach the specification of vitrified ceramic tiles.
