At present, traditional coprecipitation methods are commonly used to prepare LATP. However, the LATP solid electrolytes prepared by this method possess low purity and crystallinity, multiple impurities, and difficulty in controlling grain size and morphology. These seriously restrict the improvement of ion conductivity of LATP@PEO composite solid electrolytes. Based on this, in this work, LATP was prepared by a continuous microfluidic coprecipitation method. Compared with the traditional coprecipitation method, the crystallinity of LATP obtained by the continuous microfluidic coprecipitation method was higher and the particle size dispersion was more uniform. Furthermore, it has been found that LATP@PEO composite solid electrolytes with high ionic conductivity (1.23 × 10<sup>-5</sup> S cm<sup>-1</sup>) and low impedance (470 Ω) were obtained through a solution pouring method. The results show that the LATP obtained by continuous microfluidic coprecipitation is more conducive to improving the ionic conductivity and reducing the impedance of the LATP@PEO composite solid electrolytes than the LATP obtained by the traditional coprecipitation method. This finding suggests that the continuous microfluidic coprecipitation method would be the potential choice to prepare LATP solid electrolytes, and it possesses great prospects of industrial applications in the future.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 3","pages":"1376 - 1384"},"PeriodicalIF":2.1,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plasma technology, characterized by its high thermal performance, concentrated energy, significant chemical activity, rapid cooling rates, and controllable reaction atmospheres, has found extensive applications in this field. This paper reviews the advancements in plasma technology as applied to powder metallurgy, auxiliary combustion, and iron and steel production. In powder metallurgy, notable methods include discharge plasma sintering and plasma assisted combustion. In ironmaking, technologies such as plasma ironmaking and plasma direct reduction of iron oxide are employed. In steelmaking, plasma is utilized for melting, refining, and tundish heating processes. Currently, the application of plasma in sintering and auxiliary combustion remains limited, and there is a notable lack of in-depth research on direct reduced iron. Additionally, plasma metallurgy faces challenges, including short equipment lifespan, difficulties in controlling process parameters, and high costs. This paper proposes measures and methods to address these challenges, aiming to provide technical support for the large-scale application of plasma technology in metallurgy.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 3","pages":"1475 - 1493"},"PeriodicalIF":2.1,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of these test rigs is the PWC (pressurized water capsule), which can be used for fuel transient testing. This PWC irradiation rig was recently modified and adapted to allow for instrumented fuel pin testing. One of the key components that was successfully developed and tested is the so-called instrumentation plug, that allows the leak-tight feedthrough of three signal cables. Furthermore, a series of tests and exercises was carried out with a dummy fuel pin, showing that an instrumented fuel pin could be mounted in the newly developed PWC rig in a hot cell environment using tele-manipulators. One of the first applications is the testing of instrumented fuel pins up to incipient melting in the framework of the P2M-project (power-to-melt and maneuverability), which is a joint undertaking of SCK CEN with CEA and EDF. In this project, EDF provided a pre-irradiated fuel pin, CEA equipped the fuel pin with a centerline thermocouple and a pressure sensor, and SCK CEN is carrying out the irradiation test in the PWC rig of BR2.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 3","pages":"1305 - 1314"},"PeriodicalIF":2.1,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
