Abstract

In present work, a simple and direct method was proposed, which could be applied for quantitatively calculating the percentage of 90° domain reorientation in the tetragonal phase of KNNLN ceramics. The relationship between 90° domain reorientation and poling field was established through the X-ray diffraction analysis. Experimental results indicate that the poling field of 5 kV/mm is sufficient for the reorientation of 90° domain and while the percentage of 90° domain reorientation 37.9% and piezoelectric constant 232 pC/N are obtained. The general trend of piezoelectric properties corresponds well with that of the percentage of 90° domain reorientation.
