Abstract
1487203 Piezoelectric elements NATIONAL RESEARCH DEVELOPMENT CORP 21 Feb 1975 [28 Feb 1974] 9236/74 Heading H1E [Also in Division H4] Piezoelectric rods for use in a vibration monitor are composed of approximately a 50 : 50 mol. ratio of lead nickel niobate to lead zirconate titanate. Within the lead zirconate titanate the mol ratio of lead zirconate to lead titanate corresponds approximately to 30 : 70.
