High-performance piezoelectric material optimizes voltage charge coefficients

March 20, 2013 // By Paul Buckley
Morgan Technical Ceramics has extended the company’s material portfolio with the launch of a new piezoelectric material.

PZT5K1 is suitable for applications in the fields of scientific instrumentation, maritime, medical, energy harvesting and general industry.

PZT5K1 is just one of a range of Lead Zirconate Titanate materials – more commonly known as PZT – supplied by Morgan Technical Ceramics. The new material is suitable for a wide range of demanding and challenging applications in both emerging and existing technologies. The material’s high density and low porosity mean the material can be used for machining 1-3 composite structures in highly sensitive sonar and medical ultrasonic transducers, as well as high-performance actuators, specialist sensors and energy harvesting devices.

Using an innovative new core process, Morgan Technical Ceramics manufactures the material to offer optimised voltage charge coefficients. The material’s high d33 rating improves the electrical charge generated in energy harvesting applications, while its high d31 coefficient enhances the levels of displacement in actuators.

PZT5K1 components can be manufactured in a wide range of geometries and dimensions, with Morgan Technical Ceramics offering the capability to tailor solutions to meet individual requirements. Bimorph components are available in a variety of sizes and shapes, as squares, rectangles and discs. Sizes range from 6mm to 74 mm in length and 1mm to 43 mm in width. Discs and components up to 254 mm in diameter can be manufactured in an extensive range of thicknesses, between 3 mm and 35 mm.

Components are typically supplied with fired-on silver electrodes as standard to ensure good adhesion for soldering and bonding, and to a thickness which provides assured durability for the planned application. Other metallisation options include thin nickel electrodes to further improve coupling coefficients, while enhancing the sensitivity of sensor devices.
