The nucleation and crystallization kinetics of new glasses obtained by melting mixtures of a
Spanish carbon fly ash with glass cullet and dolomite slag at 1500°C has been evaluated by a
calculation method. These glasses, whose microstructure was examined by TEM carbon replica,
were susceptible to controlled crystallization in the 800°–1100°C range. The resulting glassceramics
developed acicular and branched wollastonite crystals or a network of dendritic
pyroxene mixed with anorthite feldspar (SEM and EDX analysis). The time–temperature–
transformation curves (processing of the XRD data) showed the crystallization kinetics and the
critical cooling rate to be in the 12°–42°C/min range.
