Abstract:
     This invention relates to wolfram-bronze type modified lead barium sodium niobate piezoeletric ceramic material, and features simple manufacture technology, good repeatability, higher coercive field strength, high anti-alternating current depolarization, good linear displacement with change of voltage and basically returning zero characteristics, fit for high accurcy piezoeletric micropotentiometer. This material contains PbO 26-36%(wt.),and Na2O or Li2O 1-3% (wt) which are prior recommended.
