Piezoelectric Crystals
Piezoelectric crystals are materials that exhibit both the direct and inverse piezoelectric effects. These crystals have a wide range of applications, including in piezoelectric sensors, sonar detection, and ultrasonic transducers for medical imaging.
EBO (a leading manufacturer in the field) achieved small-batch production of PMN-PT crystals as early as 1999. Over the years, the company has continually advanced its production capabilities and has now entered mass production in 2024, meeting the growing demand for high-performance piezoelectric materials in various industries.
EBO’s expertise in PMN-PT production allows them to offer customized solutions tailored to specific customer requirements. Whether in terms of size, shape, or electrical properties, EBO can produce PMN-PT crystals with varying dimensions and performance characteristics to meet the precise needs of different applications, from medical devices to aerospace technologies.
Quartz crystal: This is a natural piezoelectric crystal with a chemical composition of silicon dioxide. It has stable physical and chemical properties. It has good mechanical properties, and its piezoelectric properties are less affected by temperature. Therefore, it is widely used in the manufacture of high-precision oscillators, filters and other electronic components, such as frequency control components in quartz clocks.
Lithium tantalate crystal: It has a high Curie temperature (about 660°C) and can still maintain good piezoelectric properties in high temperature environments. It is often used to make high-temperature sensors, infrared detectors, etc.
Lithium niobate crystal: It is a widely used artificial synthetic piezoelectric crystal with a large electromechanical coupling coefficient and a more sensitive response to electric fields and mechanical stress. It can be used to make optical waveguides, optical modulators, surface acoustic wave devices, etc.
Barium titanate crystal: It is a ferroelectric crystal with a strong piezoelectric effect. It has a high dielectric constant and is often used to make capacitors, piezoelectric sensors, etc.
Lead zirconate titanate crystal: It is a piezoelectric ceramic crystal with excellent performance. By adjusting the ratio of zirconium (Zr) and titanium (T), its piezoelectric properties can be changed over a large range. It is widely used in sensors, actuators, ultrasonic transducers and other fields.
Piezoelectricity: This is the most important characteristic of piezoelectric crystals, which can realize the mutual conversion between mechanical energy and electrical energy with high conversion efficiency.
Stability: Within a certain range of environmental conditions such as temperature and humidity, the piezoelectric performance of piezoelectric crystals is relatively stable, which can ensure its reliability in different working environments.
Frequency characteristics: The vibration frequency of piezoelectric crystals is related to factors such as its geometric size, shape and material properties. Vibration of a specific frequency can be obtained by precisely controlling these parameters, with high frequency stability and accuracy.
Mechanical properties: Many piezoelectric crystals have good mechanical strength and hardness, can withstand a certain degree of external force without being easily damaged, and also have good elasticity, which can repeatedly undergo elastic deformation within a certain range.
