Description:

K-182 is a modified lead zirconate titanate ceramic similar to K-181, but offering a higher dielectric constant. With a low dielectric constant, high shear coupling, and stability across temperature ranges, K-182 provides the market with options to PZT-2. Applications include large diameter, and/or high frequency, high power radiators such as sonar, medical therapeutic products, and HIFU applications.
