The nucleation and crystallization of thin layers of glasses (glazes)
over ceramic substrates during the fast firing of tiles for pavements
and wall files has been a topic of great interest for tile and ceramic
paving industries in recent years. Here a wide range of glass-ceramic
compositions having different types of crystallization microstructure
has been investigated. Based on observations by scanning electron mic
roscopy and energy-dispersive X-ray microanalysis, several aspects of
nucleation and crystallization of these new types of glass-ceramic gla
zes are presented and discussed. (C) 1998 Elsevier Science Ltd.
