Ferroelectric and Piezoelectric Analyzer

Ferroelectric piezoelectric analyzer is an instrument used to study the ferroelectric and piezoelectric properties of materials. It measures the response of materials to electric fields and mechanical stress in order to analyze their ferroelectric and piezoelectric properties. Such instruments are commonly used to study the physical and electrical properties of materials, as well as for applications in areas such as electronic devices and sensors.

Sample Requirements

• The powder needs to be compressed into tablets before testing.
• Thin film can measure sample thickness 1-200 μm, area 0.0314-2 cm². Electrodes are coated on both sides, the sample thickness is greater than 1 μm, and the electrode area is greater than 0.0314 mm².
• The diameter of bulk ceramics is 0.5 - 3 cm, and the thickness is 0.1 - 2 mm. For electrodes coated on both sides, the electrode area, thickness, test frequency and electric field information are required.
• The sample thickness and electrode area should be provided.

FAQ

Q1. Why is polarization treatment required before piezoelectric testing?

A. Before the piezoelectric ceramic material is polarized, the free electrons are arranged in disorder; after the polarization treatment, the remanent polarization is generated along the polarization direction to become an anisotropic polycrystalline, the orientation of the free electrons is consistent, and the piezoelectric performance is greatly enhanced. The material can be made into any shape and any polarization direction. Piezoelectric ceramic materials before and after polarization have different dielectric constants and piezoelectric constants.

Q2. What are the prerequisites for testing piezoelectric performance?

A. Before testing the piezoelectric coefficient, the sample needs to be prepared as a block, and the thickness should be as thin as possible to ensure that the sample can be fully polarized. In addition, the samples need to prepare electrodes and undergo polarization treatment before testing.

Q3. Selection requirements for electrode types.

A. When the test temperature is lower than 500°C, silver electrodes can be used. When the test temperature is greater than 500°C and less than 800°C, gold electrodes can be used. When the test temperature is higher than 800°C, platinum electrodes should be prepared.
