Relationship Between Thermal Expansion Coefficient and Ionic Conduction in Perovskite-Type Oxides Taniguchi, Sachi Aniya, Masaru 谷口, 祥 安仁屋, 勝 ©2010 The Physical Society of Japan 427 thermal expansion coefficient oxygen ionic conductivity ionicity perovskite oxides chemical bonding application/pdf 論文(Article) The thermal expansion coefficient of complex perovskite-type oxides increases with the increase in the oxygen ionic conductivity. In the present study, with the aim to explain such a behavior, a research has been carried out from a chemical bond point of view. The ionicity fiµ of the individual bond µ, A–O and B–O bonds, and the thermal expansion coefficient of A1-xA'xB1-yB'yO3-δ were estimated theoretically. It is found that the oxygen ionic conductivity and the thermal expansion coefficient decrease with the increase in the difference of ionicity Δfi. http://jpsj.ipap.jp/link?JPSJS/79SA/106/ 社団法人 日本物理学会 2010-03-25 eng conference paper AM http://hdl.handle.net/2298/14579 https://kumadai.repo.nii.ac.jp/records/23621 Journal of the Physical Society of Japan 79 (2010) Supplement A 106 108 https://kumadai.repo.nii.ac.jp/record/23621/files/Manuscript JPSP 79 _2010_ Sup A 106 Taniguchi-r.pdf application/pdf 288.8 kB 2020-03-02
