The raw material, hematite (Fe2O3), was reduced with various amounts of coke (0.12, 0.24 and 0.36 g) at reduction temperatures of 600, 700 and 800˚C. According to the yield percent of synthesised samples, the optimum conditions were found to be 0.24 g (coke) and temperature at 700˚C. The synthesised samples were characterised by XRD, SEM and FT IR analyses. The XRD results of M47 and M48 samples reduced at 700 and 800˚C indicated the diffraction peaks correspond to the (2 2 0), (3 1 1), (4 0 0), (5 1 1) and (4 4 0) crystallographic orientations of the cubic phase of magnetite (Fe3O4) and the average crystallite sizes were 39.36 and 12.55 nm. SEM images showed that the morphologies of M47 and M48 samples were spherical in shape and partially aggregated structures. FT IR analysis of both samples revealed that the formation of the Fe-O bond was occurred at 555 and 542 cm-1."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "hematite"}, {"interim": "coke"}, {"interim": "magnetite"}, {"interim": "magnetizing reduction method"}, {"interim": "crystallite size, morphologies"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2024-02-12"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "Lai Lai Myo (315 to 326 ).pdf", "filesize": [{"value": "888 KB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_0", "mimetype": "application/pdf", "size": 888000.0, "url": {"url": "https://meral.edu.mm/record/9305/files/Lai Lai Myo (315 to 326 ).pdf"}, "version_id": "42877522-8200-4a65-8f1a-168c318c4de1"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_issue": "2022", "subitem_journal_title": "University of Yangon Research Journal", "subitem_pages": "315-326", "subitem_volume": "11, No. 1"}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Lai Lai Myo"}, {"subitem_authors_fullname": "Khin Ei Ei Thein"}, {"subitem_authors_fullname": "Cho Cho"}]}]}, "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": "2022-12-31"}, "item_title": "Characteristic Studies of Synthesised Magnetite Fe3O4", "item_type_id": "21", "owner": "12", "path": ["1582967633684"], "permalink_uri": "https://meral.edu.mm/records/9305", "pubdate": {"attribute_name": "Deposit date", "attribute_value": "2024-02-12"}, "publish_date": "2024-02-12", "publish_status": "0", "recid": "9305", "relation": {}, "relation_version_is_last": true, "title": ["Characteristic Studies of Synthesised Magnetite Fe3O4"], "weko_shared_id": -1}
