The aim of this paper is to investigate the effects of Sr, Ba and Sn on the crystal structures, surface morphologies and dielectric properties of CaTiO3 ceramics. The crystallographic phases of the ceramics were identified by X-ray diffractometer (XRD) and confirmed that all the ceramics were crystallized into orthorhombic perovskite phase. The surface morphologies and average grain sizes of the ceramics were determined using scanning electron microscopy (SEM) and verified that the crystallite particles were agglomerated form. The average grain sizes were found to be ranging from 0.383 μm to 0.436 μm. The capacitance-voltage (C-V) measurements were performed at the frequency range from 1 kHz to 1000 kHz using a LCR meter. The highest dielectric constant was occurred in the CaSn0.1Ti0.9O3 ceramic at the frequency range of 1 kHz. The dielectric constant is an important parameter of a dielectric material for the technological application of energy and data storage. From 1/C2 versus V graph, the effective dopant concentrations of the ceramics were also evaluated. The effective dopant concentrations of the ceramics were changed with the different doping materials and the maximum value was observed in the CaSn0.1Ti0.9O3 ceramic."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "Doped CaTiO3 ceramics"}, {"interim": "LCR meter"}, {"interim": "dielectric constant"}, {"interim": "effective dopant concentration Introduction"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2024-05-03"}], "download_preview_message": "", "file_order": 0, "filename": "May Kalayar Kyaing (299 to 308).pdf", "filesize": [{"value": "661 KB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_0", "mimetype": "application/pdf", "size": 661000.0, "url": {"url": "https://meral.edu.mm/record/9442/files/May Kalayar Kyaing (299 to 308).pdf"}, "version_id": "8585e65f-8df1-47ed-aa2f-067a5e3054eb"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_issue": "2022", "subitem_journal_title": "University of Yangon Research Journal 2022", "subitem_pages": "299-308", "subitem_volume": "Vol. 11, No.2"}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "May Kalayar Kyaing"}, {"subitem_authors_fullname": "Amy Aung"}, {"subitem_authors_fullname": "Ohnmar Swe"}, {"subitem_authors_fullname": "Shwe Sin Oo"}]}]}, "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": "Effects of Strontium, Barium and Tin Doping on Electrical Properties of Calcium Titanate Ceramics for Capacitor Applications", "item_type_id": "21", "owner": "235", "path": ["1582967549708"], "permalink_uri": "https://meral.edu.mm/records/9442", "pubdate": {"attribute_name": "Deposit date", "attribute_value": "2024-05-03"}, "publish_date": "2024-05-03", "publish_status": "0", "recid": "9442", "relation": {}, "relation_version_is_last": true, "title": ["Effects of Strontium, Barium and Tin Doping on Electrical Properties of Calcium Titanate Ceramics for Capacitor Applications"], "weko_shared_id": -1}
