A reversible high-temperature electrochemical cell was fabricated using alumina-dispersed zirconia as the electrolyte, lanthanum strontium manganate as the air electrode, and nickel-ziconia based cermet as the fuel one. The power generation characteristic of the fuel cell under millimeter wave irradiation was 32% higher than that of a conventional electric furnace temperature heating, and the steam electrolysis efficiency was also 120% higher under millimeter-wave irradiation than that under conventional one. Impedance measurements using an air electrode-electrolyte half-cell showed that the millimeter wave irradiation facilitated the dissociation of oxygen molecule and/or diffusion of oxygen atoms on the surface of the air electrode as well as the oxide ion conduction in the electrolyte.","PeriodicalId":35600,"journal":{"name":"Funtai Oyobi Fummatsu Yakin/Journal of the Japan Society of Powder and Powder Metallurgy","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135354792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The synthesis was carried out by the flux method, in which acicular α-Fe2O3 particles reacted with BaCO3 in NaCO3 flux. The acicular-shaped BaFe12O19 particles grown in the c-axis direction were obtained. The acicular shape consisted of aggregates of plate-like particles stacked along the c-axis. The platelet-shaped BaFe12O19 particles prepared from spherical α-Fe2O3 under the same synthesis conditions exhibited a smaller coercivity than the acicular BaFe12O19 particles synthesized in this study. Therefore, it can be inferred that the shape anisotropy has an effect on the magnetic properties of the acicular particles.","PeriodicalId":35600,"journal":{"name":"Funtai Oyobi Fummatsu Yakin/Journal of the Japan Society of Powder and Powder Metallurgy","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135354794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The raw oxide powders were mixed for 5 min using a high-energy mill. Subsequently, solid-state reaction and sintering were simultaneously performed for approximately 20 min using a spark plasma sintering apparatus. The sintering temperatures were set to 1150–1500°C for SrAl2O4: Eu, Dy and 1100–1400°C for CaAl2O4: Eu, Nd. The X-ray diffraction patterns showed that a sintering temperature of 1400°C or higher was required for single-phase synthesis of SrAl2O4: Eu, Dy, while a sintering temperature of 1200°C was suitable for synthesis of CaAl2O4: Eu, Nd. The sintered SrAl2O4: Eu, Dy and CaAl2O4: Eu, Nd phosphors exhibited bright green and blue emission by ultraviolet irradiation, respectively, and they showed afterglow properties. In particular, SrAl2O4: Eu, Dy prepared at 1500°C and CaAl2O4: Eu, Nd prepared at 1200°C showed good performance in terms of both the initial emission intensity and afterglow properties. Thus, sintered long-lasting SrAl2O4: Eu, Dy and CaAl2O4: Eu, Nd phosphors can be prepared by a short process using spark plasma sintering if the sintering temperatures are properly selected.","PeriodicalId":35600,"journal":{"name":"Funtai Oyobi Fummatsu Yakin/Journal of the Japan Society of Powder and Powder Metallurgy","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135355125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
