摘要：
Glass Samples were prepared by conventional melt quenching technique. These glass samples were converted to glass-ceramics by following two stage heat treatment schedule. The density, dielectric constant and volume fraction of PbTiO3 in glass-ceramic samples have been observed to increase with Al2O3 addition. The observed increase in the above properties has been attributed to formation of tetragonal PbTiO3 phase in the glass-ceramics. All the glass-ceramic samples exhibited the ferroelectric hysteresis loop. The value of remnant polarization was observed to increase with Al2O3 addition. The enhancement in the values of remnant polarization may be attributed to increase in the volume fraction of PbTiO3 phase in glass-ceramics.
