In addition to standard piezo-ceramic materials we also supply poreless material, as used in the BLT series ultrasonic transducers. Poreless piezoceramic has much higher specific (ultrasonic) power density, high strength, wide amplitude characteristics, low aging rate, and extremely low porosity in comparison to any other piezoceramics. These graphs demonstrate the exceptional properties of this material.
