Structures and properties of lead-free NKN piezoelectric ceramics

In this work, the preparation of sodium potassium niobate (Na 0.5K0.5)NbO3 (NKN) ceramics were carried out by the conventional method. The effect of calcination temperatures, dwell time and heating rate on phase formation was investigated. Earlier work reported that to achieve the density of NKN cer...
