Bi2SiO5晶体主要具有介电、热电以及非线性光学等性质,它的非中心对称的晶体结构使其有可能具有铁电性质。由于Bi2SiO5是亚稳态,晶体生长方面的困难,有关Bi2SiO5晶体各种性能应用的报道尚缺。本文从Bi2SiO5的晶体结构、Bi2SiO5亚稳相平衡及Bi2SiO5亚稳相的制备方法三个方面,阐述Bi2SiO5亚稳相的研究进展。
Bi2SiO5 crystal has many properties such as dielectric character,thermoelectricity,and nonlinear optics,and so on.The non-centrosymmetric crystal structure makes it possible to have ferroelectric property.Because Bi2SiO5 is a metastable compound,it is difficult to grow crystals.Now the reports on applications of various performances about Bi2SiO5 crystal are scarce.In this paper,research development of Bi2SiO5 metastable phase is expounded from three aspects on Bi2SiO5 crystal structure,Bi2SiO5 metastable phase equilibrium and preparation methods of Bi2SiO5 metastable phase.
