Piezo Technologies' K-740 is a fine grain ceramic without the compromises; a modified lead zirconate titanate piezoelectric ceramic that has a high coupling, and very high dielectric constant and piezoelectric constant. The high permittivity and high piezoelectric constant make it an excellent choice for 1-3 composites, and actuator applications.

The design and process created a fine grain ceramic that enhances the performance properties important to high frequency and fine pitch transducer designs. This next generation piezo material redefines the standard for fine grain ceramics.

$Competitor's product at 48000x, fractured surface - Fine grain size with less fracture toughness creates intergranular fractures when the ceramic is broken or diced, resulting in non-uniform fine pitch elements.$

Piezo Technologies' new Fine Grain Ceramics offer the following benefits:

A less porous, more uniform fine grain structure - a new standard.
Fine grain size enhances structural and performance uniformity of fine pitch transducer designs.
Higher dielectric constant, d₃₃ and Q_M versus similar grain structured designs.
A reliable second source for competitor's ceramic.
A viable first choice for fine pitch designs where enhanced performance and element to element uniformity is required.
