Material class:

Lead Metaniobate

Reviewed:

Yes

Description:

Modified lead metaniobate ceramic with a low mechanical Q, negligible aging of the piezoelectric parameters, a low acoustic impedance and a relatively high piezoelectric strain constant for higher signal to noise ratio. Primary application is broadband width sensors for pulse-echo measurement in medical or NDT application. Specially designed for immersion application.
