The high-temperature pyroelectric testing system is a precision instrument used to measure the pyroelectric coefficient of pyroelectric materials in high-temperature environments. Its pyroelectric performance is evaluated by analyzing the surface charge changes generated by the material during temperature changes.
The pyroelectric effect refers to the phenomenon where the spontaneous polarization intensity of a material changes with temperature, resulting in induced charges on the crystal surface perpendicular to the polarization direction. The high-temperature pyroelectric testing system measures the pyroelectric current released by the pyroelectric material during the uniform heating process, and calculates the intrinsic pyroelectric coefficient of the material by combining it with the temperature change rate.
Function:
Measurement of pyroelectric coefficient: During the uniform heating process, the intrinsic pyroelectric coefficient is calculated by detecting the current released by the material, which is suitable for materials of different shapes such as thin films, thick films, single crystals, ceramics, etc.
Temperature control: It can achieve high temperature environment control from RT (room temperature) to 400 ℃, with a temperature control accuracy of ± 0.1 ℃, and supports a heating and cooling rate of 1-10 ℃/min.
Data collection and analysis: Automatically record the variation curve of pyroelectric current during the heating process and generate test reports for performance evaluation in scientific research or industrial applications.
