摘要：

Several glazes were obtained for an application onto the surface of clay-based ceramic tiles that are usually produced by fast firing. Original glasses within the F-K2O-CaO-SiO2 system were obtained and during the sinter- crystallization of glass ceramic, fluoride-miserite (KCa5Si8O22F2) nanocrystals with an amount of 4.5 % F-2 were precipitated in the glassy matrix. These glassy tiles can be used for floor and wall coverings in buildings, for certain decorations in civil engineering and for pavements exhibiting good wear and anti-slip properties. The TEM-replica and extraction-replica methods were revisited for observing the microstructures of these glasses under the conventional TEM to elucidate clearly the phase separation that gives rise to the opalescence of these glasses and is strongly dependent on the fluorine included in the structures of these glasses.
