For the (KxNa1-x)NbO3 piezoceramics,earlier publications described that there are three phase boundaries corresponding approximately to x=0.17,0.35,0.5 respectively1.Since 2004,many studies have been focused on the composition at about x=0.5 because of the significant improvement of piezoelectric properties2.
