Fatigue Testing Method and Property Changes of Piezoelectric Ceramics

Development, Characterization, and Piezoelectric Fatigue Behavior of Lead- Free Perovskite Piezoelectric Ceramics

The development of lead-free perovskite piezoelectrics as environmentally compatible alternatives to lead zirconate titanate (PZT) has received significant attention recently. Two main categories of lead free perovskite piezoelectric ceramic systems were investigated as potential replacements to lead zirconate titantate (PZT) for actuator devices. First, solid solutions based on Li, Ta, and Sb ...

Characterisation of Piezoelectric Ceramics

The IEEE standard on piezoelectricity recommends methods to determine the coefficients of piezoelectric ceramics and the sizes of the samples to be used. A method to determine the difference between the actual coefficients and the coefficients determined using the IEEE standard is presented. The difference or error for samples of various shapes and sizes is presented. These errors and manufactu...

Piezoelectric Ceramics Characterization

This review explores piezoelectric ceramics analysis and characterization. The focus is on polycrystalline ceramics; therefore, single crystals, polymeric materials and organic/inorganic composites are outside the scope of this review. To thoroughly grasp the behavior of a piezoelectric polycrystalline ceramic, a basic understanding of the ceramic itself should not be overlooked. To this end, w...

pharmaceutical application of nanocrystalline piezoelectric ceramics

Fatigue of dental ceramics.

OBJECTIVES Clinical data on survival rates reveal that all-ceramic dental prostheses are susceptible to fracture from repetitive occlusal loading. The objective of this review is to examine the underlying mechanisms of fatigue in current and future dental ceramics. DATA/SOURCES The nature of various fatigue modes is elucidated using fracture test data on ceramic layer specimens from the denta...
