Enhanced grain growth in lead-free (1-x)(Na<inf>0.5</inf>Bi<inf>0.5</inf>)TiO<inf>3</inf>- XAgNbO<inf>3</inf>solid solution ceramics

The lead-free (1-x)(Na 0.5 Bi 0.5 )TiO 3 - xAgNbO 3 (x = 0.00-0.15) ceramics were synthesized by solid state reaction. Anomaly large grain growth was observed by scanning electron microscopy with an average grain size reaching 90 μm for x = 0.02. The incorporation of AgNbO 3 into (Na 0.5 Bi 0.5 ) Ti...
