Lead-free piezoceramics

Nature, 2004
Lead has recently been expelled from many commercial applications and materials (for example, from solder, glass and pottery glaze) owing to concerns regarding its toxicity. Lead zirconium titanate (PZT) ceramics are high-performance piezoelectric materials, which are widely used in sensors, actuators and other electronic devices; they contain more ...

Lead-free multilayer piezoelectric transformer [PDF]

Review of Scientific Instruments, 2007
In this article, a multilayer piezoelectric transformer based on lead-free Mn-doped 0.94(Bi1∕2Na1∕2)TiO3–0.06BaTiO3 ceramics is presented. This piezoelectric transformer, with a multilayered construction in the thickness direction, is 8.3mm long, 8.3mm wide, and 2.3mm thick. It operates in the second thickness extensional vibration mode.

Lead-free acoustic emission sensors [PDF]

Review of Scientific Instruments, 2007
Acoustic emission (AE) sensors have been fabricated using both soft- and hard-type lead-free (Na0.5K0.5)NbO3-based ceramics. The acoustic and electromechanical properties of the ceramics have been determined using the resonance technique. The lead-free AE sensors were calibrated using a laser source and compared to a commercial sensor. A lead zirconate

Lead‐Free Relaxor Ferroelectrics

Journal of the American Ceramic Society, 2011
Feature size is a natural determinant of material properties. Its design offers the technological perspectives for material improvement. Grain size, crystallite size, domain width, and structural defects of different nature constitute the classical design elements.

Lead‐free alloys

Soldering & Surface Mount Technology, 1998
In recent years, efforts to develop alternatives to lead‐based solders have increased dramatically. These efforts began as a response to potential legislation and regulations restricting lead usage in the electronics industry. Lead is extremely toxic when inhaled or ingested. As researchers began to focus on Pb‐free solders, they recognized their value

Lead-Free Piezoelectric Transducers

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control
Research activities on lead-free piezoelectric materials have been ongoing for over 20 years. Generally, the applicability of the main material families is less universal than that of lead-based compositions such as lead zirconate titanate, but in some cases, the corresponding applications have already been identified. Due to the extensive research, it
