The materials with perovskite structure is orthorhombic phase at x?0.05 and becomes tetragonal phase at x?0.07, a phase K3Li2Nb5O15 with tetragonal tungsten bronze structure begins to appear at x=0.08 and becomes dominant with increasing the content of LiNbO3. A morphotropic phase boundary between orthorhombic and tetragonal phases is found in the composition range 0.05<x<0.07. Analogous to Pb(Zr,Ti)O3, the piezoelectric and electromechanical properties are enhanced for compositions near the morphotropic phase boundary. Piezoelectric constant d33 values reach 200-235 pC/N. Electromechanical coefficients of the planar mode and the thickness mode reach 38%-44% and 44%-48%, respectively. The Curie temperatures (TC) of [Lix(Na0.5K0.5)1-x]NbO3 (x=0.04-0.20) are in the range of 452-510°C, at least 100°C higher than that of conventional Pb(Zr,Ti)O3. Our results show that [Lix(Na0.5K0.5)1-x]NbO3 is a good lead-free high-temperature piezoelectric ceramic.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_full_name_27":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"8759","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000040335089","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000040335089"}],"names":[{"name":"柿本, 健一"}]},{"nameIdentifiers":[{"nameIdentifier":"17712","nameIdentifierScheme":"WEKO"}],"names":[{"name":"大里, 齊"}]}]},"item_10001_publisher_29":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Institute of Physics","subitem_publisher_language":"en"}]},"item_10001_relation_34":{"attribute_name":"item_10001_relation_34","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1063/1.1813636"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1063/1.1813636","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_30":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0003-6951","subitem_source_identifier_type":"ISSN"}]},"item_10001_source_id_32":{"attribute_name":"item_10001_source_id_32","attribute_value_mlt":[{"subitem_source_identifier":"AA00543431","subitem_source_identifier_type":"NCID"}]},"item_10001_version_type_33":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Guo, Yiping","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"17708","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kakimoto, Ken-ichi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"8759","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000040335089","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000040335089"}]},{"creatorNames":[{"creatorName":"Osato, Hitoshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"17710","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-01-25"}],"displaytype":"detail","filename":"APL 85_4121.pdf","filesize":[{"value":"198.7 kB"}],"format":"application/pdf","license_note":"Copyright (2004) American Institute of Physics.
