Lead Zirconate Titanate (HIFU)

NEW! Ferroperm Piezoceramics have developed two new PZT materials with properties specifically optimised for high-intensity focused ultrasound (HIFU). The main features are a high permittivity and high coupling combined with low dielectric and mechanical losses.

Type Pz52: This material is based on the traditional family of piezoceramic materials. It has a moderately high permittivity and a high operating temperature.
It is specially suited for substitution of the traditional Type 100 materials, in applications where the required power level is higher than this material can handle without problems of overheating and depoling.

Type Pz54: This material is based on the newly developed relaxor based solid solution family. It has a very high permittivity and a working temperature, which is comparable to Pz52. It is optimised for use in highly specialised HIFU transducers, where demands for the power level versus size are very critical.

Type Pz34: A material exhibiting a large electromechanical anisotropy, low dielectric constant and properties stable with time, temperature and frequency. Recommended for applications where interference with radial modes is a significant problem and for high frequency applications due to the low dielectric constant.

Type Pz35: A highly anisotropic material, with a low mechanical quality factor and low dielectric constant. This material is primarily used in NDT systems where low Q_m and clean impulse response are required.
