The micrographs of the ceramics reveal that the grains grow up from 2 μm to about 10 μm with increasing the sintering time. The optimization of the sintering time is found to be a simple and effective way to largely enhance the TCR values of the ceramics. The highest metal–insulator transition temperature Tp (272.5 K) and the largest TCR (21.4%) were obtained in the ceramic sintered for 12 h. The reduction of grain boundary and resistivity contributes to the enhancement of Tp and TCR values."}]},"item_1583103108160":{"attribute_name":"Keywords","attribute_value_mlt":[{"interim":"Sol–gel"}]},"item_1583103120197":{"attribute_name":"Files","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2020-05-05"}],"displaytype":"preview","filename":"Enhancement of temperature coefficient of resistivity in La0.67Ca0.33MnO3 polycrystalline ceramic.pdf","filesize":[{"value":"1417 Kb"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://meral.edu.mm/record/2131/files/Enhancement of temperature coefficient of resistivity in La0.67Ca0.33MnO3 polycrystalline ceramic.pdf"},"version_id":"cc685935-04f3-4545-a22e-d43c729a2f3a"}]},"item_1583103131163":{"attribute_name":"Journal articles","attribute_value_mlt":[{}]},"item_1583103147082":{"attribute_name":"Conference papaers","attribute_value_mlt":[{}]},"item_1583103211336":{"attribute_name":"Books/reports/chapters","attribute_value_mlt":[{}]},"item_1583103233624":{"attribute_name":"Thesis/dissertations","attribute_value_mlt":[{"subitem_supervisor(s)":[]}]},"item_1583105942107":{"attribute_name":"Authors","attribute_value_mlt":[{"subitem_authors":[{"subitem_authors_fullname":"Ma, Ji"},{"subitem_authors_fullname":"Cai, Yunqi"},{"subitem_authors_fullname":"Wang, Wenzhang"},{"subitem_authors_fullname":"Cui, Qi"},{"subitem_authors_fullname":"Mya Theingi"},{"subitem_authors_fullname":"Zhang, Hui"},{"subitem_authors_fullname":"Chen, Qingming"}]}]},"item_1583108359239":{"attribute_name":"Upload type","attribute_value_mlt":[{"interim":"Publication"}]},"item_1583108428133":{"attribute_name":"Publication type","attribute_value_mlt":[{"interim":"Journal article"}]},"item_1583159729339":{"attribute_name":"Publication date","attribute_value":"2013"},"item_1583159847033":{"attribute_name":"Identifier","attribute_value":"http://uyr.uy.edu.mm/handle/123456789/100"},"item_title":"Enhancement of temperature coefficient of resistivity in La0.67Ca0.33MnO3 polycrystalline ceramics","item_type_id":"21","owner":"1","path":["1582967633684"],"publish_date":"2020-03-05","publish_status":"0","recid":"2131","relation_version_is_last":true,"title":["Enhancement of temperature coefficient of resistivity in La0.67Ca0.33MnO3 polycrystalline ceramics"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2021-12-13T07:02:02.250645+00:00"}
