New Ceramic Material PIC144 for Even Greater Ultrasonic PerformancePI Ceramic, Karlsruhe, Germany
PI Ceramic has developed yet another piezo material based on lead-zirconate-titanate (PZT). PIC144 belongs to the ferro-electrical hard materials and is designed specifically for use in OEM high-power ultrasonic applications.
Uniform and stable
High-power ultrasound applications are characterized by a high dynamic range, from several hundred kilohertz up to a few megahertz, as well as by high operating amplitudes. Especially during continuous operation, the key thing to achieve is to have stable oscillation properties with low mechanical and di-electrical losses, i.e. generating as little heat as possible in the converter element.
PIC144 features a large electromechanical coupling factor with a high quality factor, as well as exceptional mechanical and electrical stability.
Independent of Time and Temperature
At the same time, the converter properties of the new material are virtually independent of time and temperature, rendering them suitable for high-power applications.
PIC144 is suitable for use in ultrasonic cleaning, in materials processing, i.e. ultrasonic welding and bonding, or in ultrasonic processors. Sonar technology, acoustic methods for non-destructive materials testing (NDT in short), biotechnology applications such as scalers for removing tooth plaque, or the ultrasonic processes involved in ultrasonic surgery, all benefit from the properties of the new material.
