Properties of （K0.48 Na0.52 ） 1-x （LiSb） x Nbl-χ Os Lead-free Piezoelectric Ceramics Prepared by Composite Method
Abstract：Lead-free Piezoelectric ceramics （K0.48Na0.52）l-χ（LiSb）xNbl-xO3 （x=0. 055,0. 060,0. 065）, the composition compounded with x=0.055, x=0. 065 in mol ratio 1：1 （55-65） are fabricated by con- ventional solid-state sintering method, and the dielectric and piezoelectric characteristics are investiga- ted. It is found that the piezoelectric properties of 55-65 is much lower than that of the sample with x= 0. 060. Further investigations show that the sample 55-65 has relatively high dielectric loss and small grains. The smaller grains may lead to stronger stress with the same strain and this may be the reason for the sample 55-65 exhibiting low piezoelectric activities.
