Formation of nano-sodium niobate crystals in ferroelectric glasses and glass-ceramics of the Na2O-Nb2O5-Al 2O3-SiO2 system

Ferroelectric glasses and glass-ceramics were prepared from selected composition in the Na2O-Nb2O5-Al2O3-SiO2 glass system. Small amount of TiO2 was also added. Conventional melt-quenching technique was employed for a glass production and the selected bulk parent glass samples were subjected to the...
