Modified Lead Metaniobate Piezoelectric Ceramic for Non-Destructive Testing
Piezo Technologies' K-83 lead metaniobate piezoelectric ceramic was formulated specifically for use in non-destructive testing transducers at frequency operation of 2MHz and above in contact applications. Its low dielectric constant coupled with high frequency constant results in a lower capacity for high frequency driving.
