Effect of the NaO-NbO-PO glass additive on the structure, dielectric and energy storage performances of sodium niobate ceramics.

A phosphate glass NaO-NbO-PO (NPP) is incorporated into NaNbO (NN) ceramics to examine its impact on the density, rearrangement of structural units, dielectric and energy storage features of the elaborated composites. The sodium niobate ceramic (NN) is prepared using the solid state process, whereas, the NaO-NbO-PO (NPP) glasses are produced using the method of conventional melt quenching. The glass (NPP) is added to the ceramic (NN) according to the composition (100-x) NN-xNNP; (x = 0, 2.
