The X-ray diffraction (XRD) data revealed that a CaGa4O7 phase was precipitated by heat treatment. The Avrami index (n) of 1.7±0.2 obtained from `the Fourier transform infrared (FT-IR) transmission method' combined with the Johnson–Mehl–Avrami (JMA) equation indicated that the crystallization proceeded three dimensionally. The activation energy (Ea) of 7.2±0.3 eV obtained from the JMA plot was equal to that obtained from the Kissinger plot in the differential thermal analysis: Ea=7.1±0.2 eV. Mössbauer spectra of 40CaO·59Ga2O3·Full-size image (<1 K)2O3 samples showed the oxidation of iron from Fe2+ to Fe3+. Mössbauer spectra of the 40CaO·59Ga2O3·Full-size image (<1 K)2O3 samples irradiated with the YAG laser also showed an oxidation of Fe2+ to Fe3+. In case of Full-size image (<1 K)γ-ray irradiated samples, however, a reduction of the iron from Fe3+ to Fe2+ was observed. This result indicates that Fe3+ occupies substitutional sites of Ga3+ in the gallate glass."}]},"item_1583103108160":{"attribute_name":"Keywords","attribute_value_mlt":[{"interim":"O180"}]},"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":"Kubuki, S."},{"subitem_authors_fullname":"Nishida, T."},{"subitem_authors_fullname":"Pho Kaung"},{"subitem_authors_fullname":"Yagi, T."},{"subitem_authors_fullname":"Maeda, Y."}]}]},"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":"1997"},"item_1583159847033":{"attribute_name":"Identifier","attribute_value":"http://uyr.uy.edu.mm/handle/123456789/29"},"item_title":"Application of the IR transmission method and the Mossbauer effect to the crystallization of calcium gallate glass","item_type_id":"21","owner":"1","path":["1582967549708"],"publish_date":"2020-03-05","publish_status":"0","recid":"2674","relation_version_is_last":true,"title":["Application of the IR transmission method and the Mossbauer effect to the crystallization of calcium gallate glass"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2021-12-13T03:18:02.561164+00:00"}
