Abstract—
In this paper, we describe improved methods for assessing the static and dynamic piezoelectric properties of lithium niobate crystals. The results can be used for evaluating results of conversion of large lithium niobate crystals to a single-domain state under mass production conditions. We present main calculated relationships for assessing the degree of unipolarity and the relative volume of antiparallel domains in large lithium niobate crystals. The described techniques are applicable to other piezoelectric materials as well.
