摘要
异极矿因具有较高的热释电系数和低的介电常数,可以作为一种传感器材料应用于温度测量、红外光谱测量和催化中。然而天然异极矿成分复杂,存在类质同像替代现象和共生矿物,限制了其热释电机理分析及实际应用,因此,人们开始利用不同的合成方法探索异极矿的人工合成。本文结合目前异极矿的研究现状,综合分析了异极矿所具有的物理性能、人工合成方法及目前存在的问题,以期为后续合成成分简单的异极矿单晶、研究其热释电性产生的机理以及性能调控提供重要参考。
Since hemimorphite shows the properties of high pyroelectric coefficient and low dielectric constant,it is a potential sensor material in temperature measurement,infrared spectroscopy measurement,and catalysis fields.However,due to the isomorphism substitution in hemimorphite,the complex composition of hemimorphite limits the research on pyroelectric mechanism and the following application.Hence,researchers focus on the synthetic methods of hemimorphite with high purity.In this paper,the physical properties,synthesis methods,and remaining problems in the study of hemimorphite are reviewed based on the current research progress.The results will provide an important reference on the synthesis,the pyroelectricity mechanism,and the performance regulation of hemimorphite in the future.
