K-91

Piezo Technologies' K-91 is a modified lead metaniobate piezoelectric ceramic with the following outstanding characteristics:

• K-91 has a low acoustic impedance.
• Negligible aging of the piezoelectric constant increases the stability and reliability of transducers made from K-91.
• Extremely stable piezoelectric activity at very high temperatures (up to 300 C°)
• K-91 piezoelectric ceramic is well suited for deep water and high temperature environments and hostile transducer applications.
