Piezoelectric Materials
Several types of piezoelectric ceramic materials are available. Each type is tailored towards the requirements of particular applications. This is achieved by changing the chemical composition of the ceramic to enhance specific properties. The ceramic materials are arranged in three groups: Hard Materials, Soft Materials and Custom Materials.
High Power Hard PZT
High power or "hard" ceramics can withstand high levels of electrical excitation and mechanical stress. These materials are suited for high voltage or high power generators and transducers.
Low Field Soft PZT
Low field or "soft" ceramics feature high sensitivity and permittivity, but under high drive conditions are susceptible to self-heating beyond their operating temperature range. These materials are used in various sensors, low-power motor-type transducers, receivers, and low power generators.
Single Crystal Piezo
Morgan Technical Ceramics Electroceramics (MTC Electroceramics) announces the release of our new single crystal piezoelectric material, PMNT-28, for use in transducer and actuator devices. The new family of U.S. manufactured materials was formulated to exhibit very large electromechanical coupling coefficients and also offers high dielectric constants and low dielectric losses.
Custom
Several ceramic materials have been formulated to meet the particular needs of specific applications.
