ELABORATION OF ADVANCED GLASS-CERAMIC GLAZE FOR ANTI-SLIP PORCELAIN STONEWARE

ABSTRACT
The present communication describes the synthesis of anti-slip enamel exhibiting glass-ceramic nature using
new matte frits and raw materials. The glass-ceramic glazes obtained are characterized by various instrumental
techniques (X-ray fluorescence (XRF), scanning electron microscopy (SEM), X-ray diffraction (XRD), mechanical
profilometry and microhardness measurements) to elucidate the nature of the crystallized phases, their morphology,
surface roughness and the finished tile microhardness. The quality of the glazed piece is evaluated by the regulations
of chemical resistance, stain-resistance and slipperiness. The enamel obtained devitrifies in crystals of calcium and
barium silicoaluminates. It complies with anti-slip and stain-resistance standards, because its surface roughness is
similar to that of non-slip enamel.
