Crystallization behavior during annealing of eutectic glass in the C12A7-CaYAlO4 system was investigated by SEM, STEM, XRD, and TG-DTA. At 900 °C, phase separation of Y-poor and Y-rich phases appeared without crystallization. The phase separation might lead bulk crystallization of C12A7 by subsequent crystallization. At 950 °C, crystallization of unknown metastable phase was observed together with C12A7 crystallization. Above 1000 °C, crystallization of CaYAlO4 and C12A7 was observed. Crystallization behavior was schematically explained and bulk crystallization of C12A7 was explained by the phase separation.
