摘　　要：方硼石是一个罕见的极性矿物家族,大量针对方硼石热释电性的研究表明,方硼石在未进行任何改性的情况下就具有接近PZT等材料的热释电性能,而其结构并不是传统的钙钛矿构型,且不含有任何毒性元素,它作为一种热释电材料极具研究与应用价值。遗憾的是受限于材料质量等原因,至今方硼石的热释电机理与共性构效关系并未被阐明,因此针对方硼石的系统性改性研究还未深入开展,其热释电应用潜力也未被很好地开发。基于以上科学问题,本文综述了方硼石矿物晶体材料的人工合成方法和介电、热释电、铁电、铁磁、铁弹以及非线性光学等性质的研究进展,以期为后续进一步合成方硼石单晶、研究其本征物性以及性能调控提供重要参考。A large number of researches on the pyroelectricity of boracite,which is a rare polar mineral family,have shown that boracite has pyroelectric properties close to those of the PZT and other materials under the situation of without any modification of its properties.Its structure is not the traditional perovskite configuration and it does not contain any toxic elements.It is of great research and application value as a pyroelectric material.Unfortunately,due to the limitation of material quality and other reasons,the pyroelectric mechanism and the common constitutive relationship of boracite have not been elucidated so far.Therefore,the study on the systematic modification of boracite has not been deeply carried out,and its potential of pyroelectric applications has not been well exploited.Based on the above scientific issues,in this paper,we have reviewed the synthetic methods of the boracite mineral crystalline material and progresses of researches on its dielectric,pyroelectric,ferroelectric,ferromagnetic,ferroelastic,and nonlinear optical properties,in order to provide important references for the further synthesis of single boracite crystal,the study of its intrinsic physical properties,and the modulation of its properties.
