Among such material families, iron (Fe: 3d64s2)-containing oxides pique interest owing to their widely tunable MIT properties, which are associated with the various valence states of Fe. Their potential electronic applications also show promise, given the large abundance of Fe on Earth. Representative MIT properties triggered by critical temperature (TMIT) were reported for ReFe2O4 (Fe2.5+), ReBaFe2O5 (Fe2.5+), Fe3O4 (Fe2.67+), Re1/3Sr2/3FeO3 (Fe3.67+), ReCu3Fe4O12 (Fe3.75+), and Ca1−xSrxFeO3 (Fe4+) (where Re represents rare-earth elements). The common feature of MITs of these Fe-containing oxides is that they are usually accompanied by charge ordering transitions or disproportionation associated with the valence states of Fe. Herein, we review the material family of Fe-containing MIT oxides, their MIT functionalities, and their respective mechanisms. From the perspective of potentially correlated electronic applications, the tunability of the TMIT and its resultant resistive change in Fe-containing oxides are summarized and further compared with those of other materials exhibiting MIT functionality. In particular, we highlight the abrupt MIT and wide tunability of TMIT of Fe-containing quadruple perovskites, such as ReCu3Fe4O12. However, their effective material synthesis still needs to be further explored to cater to potential applications.","PeriodicalId":14030,"journal":{"name":"International Journal of Minerals, Metallurgy, and Materials","volume":"69 1","pages":""},"PeriodicalIF":2.232,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139578963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Scanning electron microscopy and Brunauer–Emmett–Teller theory demonstrated the microstructural evolution of the roasted product and the gradual reduction in the pyrolusite ore from the surface to the core. Thermodynamic calculations, X-ray photoelectron spectroscopy, and X-ray diffractometry analyses determined that the phase transformation of pyrolusite followed the order of MnO2→Mn2O3→Mn3O4→MnO phase by phase, and the reduction of manganese oxides in each valence state proceeded simultaneously.","PeriodicalId":14030,"journal":{"name":"International Journal of Minerals, Metallurgy, and Materials","volume":"72 1","pages":""},"PeriodicalIF":2.232,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139579069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several characterization and electrochemical techniques were used to characterize the different Ni-P coatings’ morphologies, phase structures, elemental compositions, and corrosion protection. The gradient coating showed good adhesion and high corrosion and wear resistance, enabling the application of aluminum alloy in harsh environments. The results showed that the double zinc immersion was vital in obtaining excellent adhesion (81.2 N). The optimal coating was not peeled and shredded even after bending tests with angles higher than 90° and was not corroded visually after 500 h of neutral salt spray test at 35°C. The high corrosion resistance was attributed to the misaligning of these micro defects in the three different nickel alloy layers and the amorphous structure of the high P content in the outer layer. These findings guide the exploration of functional gradient coatings that meet the high application requirement of aluminum alloy parts in complicated and harsh aviation environments.","PeriodicalId":14030,"journal":{"name":"International Journal of Minerals, Metallurgy, and Materials","volume":"59 1","pages":""},"PeriodicalIF":2.232,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139578972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thermodynamic analysis indicated the feasibility of oxidation roasting of molybdenum concentrate. The effects of roasting temperature, holding time, and power-to-mass ratio on the oxidation product and leaching product sodium molybdate (Na2MoO4·2H2O) were investigated. Under the optimal process conditions: roasting temperature of 700°C, holding time of 110 min, and power-to-mass ratio of 110 W/g, the molybdenum state of existence was converted from MoS2 to MoO3. The process of preparing sodium molybdate by alkali leaching of molybdenum calcine was investigated, the optimal leaching conditions include a solution concentration of 2.5 mol/L, a liquid-to-solid ratio of 2 mL/g, a leaching temperature of 60°C, and leaching solution termination at pH 8. The optimum conditions result in a leaching rate of sodium molybdate of 96.24%. Meanwhile, the content of sodium molybdate reaches 94.08wt% after leaching and removing impurities. Iron and aluminum impurities can be effectively separated by adjusting the pH of the leaching solution with sodium carbonate solution. This research avoids the shortcomings of the traditional process and utilizes the advantages of microwave metallurgy to prepare high-quality sodium molybdate, which provides a new idea for the high-value utilization of molybdenum concentrate.","PeriodicalId":14030,"journal":{"name":"International Journal of Minerals, Metallurgy, and Materials","volume":"3 1","pages":""},"PeriodicalIF":2.232,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139578883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The accurate prediction of thermal conductivity is a prerequisite for designing Mg−Al alloys with high thermal conductivity. Thus, databases for predicting temperature- and composition-dependent thermal conductivities must be established. In this study, Mg−Al−La alloys with different contents of Al2La, Al3La, and Al11La3 phases and solid solubility of Al in the α-Mg phase were designed. The influence of the second phase(s) and Al solid solubility on thermal conductivity was investigated. Experimental results revealed a second phase transformation from Al2La to Al3La and further to Al11La3 with the increasing Al content at a constant La amount. The degree of the negative effect of the second phase(s) on thermal diffusivity followed the sequence of Al2La > Al3La > Al11La3. Compared with the second phase, an increase in the solid solubility of Al in α-Mg remarkably reduced the thermal conductivity. On the basis of the experimental data, a database of the reciprocal thermal diffusivity of the Mg−Al−La system was established by calculation of the phase diagram (CALPHAD) method. With a standard error of ±1.2 W/(m·K), the predicted results were in good agreement with the experimental data. The established database can be used to design Mg−Al alloys with high thermal conductivity and provide valuable guidance for expanding their application prospects.","PeriodicalId":14030,"journal":{"name":"International Journal of Minerals, Metallurgy, and Materials","volume":"11 1","pages":""},"PeriodicalIF":2.232,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139579100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
