Application of pyroelectric material
The invention discloses application of a pyroelectric material. The pyroelectric material is used for collecting heat energy, the heat energy is converted into electric energy by utilizing temperaturechange, and the pyroelectric material is a porous zirconium calcium barium titanate ceramic material; the temperature change is greater than or equal to 1 DEG C; and the porosity of the porous bariumcalcium zirconate titanate ceramic material is 10-60%. The porous zirconium-calcium-barium titanate ceramic material is applied to heat energy collection for the first time, the inventor finds that the porous barium calcium zirconate titanate can be used as the pyroelectric material, and the working principle is as follows: when the environment temperature changes, the pyroelectric material has apyroelectric effect and generates voltage on the upper and lower surfaces of the material, and the heat energy is converted into the electric energy. The porous barium calcium zirconate titanate serves as the pyroelectric material to be used for heat energy collection, the condition for converting the heat energy into the electric energy is that the temperature fluctuation is larger than or equalto 1 DEG C, that is, heat energy collection can be achieved only through temperature fluctuation of 1 DEG C, and the heat energy collection efficiency is greatly improved compared with a thermoelectric material in the prior art.
本发明公开了一种热释电材料的应用，将热释电材料用于热能收集，利用温度变化将热能转化为电能，所述热释电材料为多孔锆钙钛酸钡陶瓷材料；所述温度变化≥1℃；所述多孔锆钙钛酸钡陶瓷材料的孔隙率为10％～60％。本发明首创的将多孔锆钙钛酸钡陶瓷材料应用于热能收集，发明人发现，多孔锆钙钛酸钡可作为热释电材料，其工作原理为当环境温度发生变化，热释电材料由于热释电效应，使材料的上下表面产生电压，将热能转换为电能，本发明中将多孔锆钙钛酸钡作为热释电材料用于热能收集，其热能转化为电能的条件为温度波动≥1℃，即只需有1℃的温度波动，即能实现热能收集，热能收集的效率相对于现有技术的热电材料大幅提升。
