Custom
ECD manufacturers several ceramic materials formulated to meet the particular needs of specific applications.
PZT-5B
('Datasheet MEC Navy custom i' & 'Datasheet MEC Navy custom ii' on Morgan Technical Ceramics website, requires sign up)
Has higher sensitivity and piezoelectric activity than PZT-5A, with a slightly lower Curie temperature.
PZT-5R
('Datasheet MEC Navy custom i' & 'Datasheet MEC Navy custom ii' on Morgan Technical Ceramics website, requires sign up)
This material is used in applications such as towed array lines. PZT-5R has high acoustic sensitivity, and high coupling, while maintaining high permittivity.
PZT-5M
('Datasheet MEC Navy custom i' & 'Datasheet MEC Navy custom ii' on Morgan Technical Ceramics website, requires sign up)
This material was developed for medical imaging to have very good sensitivity and high permittivity, and still maintain a good Curie temperature.
PZT-5K
(This material has a new spec – click here to find out more)
This material was developed to maximize the sensitivity and permittivity, while still achieving a Curie temperature that is workable.
PZT-7A
('Datasheet MEC Navy custom ii (b) on Morgan Technical Ceramics website, requires sign up)
This material is used in ultrasonic delay lines and other high frequency shear resonance applications. PZT-7A is a material featuring a high shear coupling coefficient with low permittivity, and high temperature stability. Its ageing characteristics are extremely low (high time stability), providing extremely low phase distortion in electrical resonance circuits.
PZT-7D
('Datasheet MEC Navy custom ii (b) on Morgan Technical Ceramics website, requires sign up)
With lower dissipation than PZT-7A, this material is used in applications requiring higher power handling capability. PZT- 7D is a modified PZT-7A material, characterized by a higher permittivity and piezoelectric activity with only a slight reduction in coupling. Its extremely low ageing characteristics provide very stable, highly reproducible operation.
PT1
('Datasheet MEC Navy custom ii (b) on Morgan Technical Ceramics website, requires sign up)
This material is a modified lead titanate and has a large piezoelectric effect in the thickness mode as compared to the radial moded. As a result of this property, this material is particularly useful in sonar receiver arrays and non-destructive testing equipment.
