Abstract: Molybdenum, a rare metal of exceptional strategic importance, is widely utilized in critical sectors such as the nuclear industry, aerospace, and electronics due to its outstanding properties. In recent years, growing global demand for molybdenum and its derivative materials has led to a persistent supply-demand gap in the industry, prompting domestic manufacturers to transition toward developing advanced molybdenum-based new materials. (Delete this sentence) This review systematically examines the types and properties of common molybdenum alloys, the fundamental characteristics of molybdenum disulfide, and the principles of mainstream preparation methods including powder metallurgy and additive manufacturing, while highlighting the applications of molybdenum derivatives across various fields. Additionally, it explores strategies for high-quality development in the molybdenum-based materials sector from three perspectives—material composition, integrated innovation in advanced fabrication processes, and industrialization of two-dimensional molybdenum-based materials—and outlines future trends. The study aims to provide theoretical foundations for fundamental research, technological advancement, and practical applications of molybdenum-based materials. (Molybdenum, a strategically important rare metal, occupies an irreplaceable position in high-end fields such as nuclear industry, aerospace, and electronics, owing to its high melting point, excellent high-temperature strength, good thermal and electrical conductivity, and corrosion resistance. With the global energy transition and upgrading of advanced manufacturing, the supply-demand gap for molybdenum materials has become increasingly prominent, and China’s molybdenum industry is shifting from resource export to high-end material manufacturing. This review systematically summarizes the research progress of molybdenum-based materials from traditional alloys to two-dimensional functional systems. First, the compositions, properties, and limitations of five commonly used molybdenum alloys—TZM, Mo-Re, Mo-W, Mo-Cu, and Mo-La2O3—are outlined. Second, the principles, advantages, and existing challenges of mainstream fabrication routes are elaborated, including powder metallurgy (mechanical alloying, isostatic pressing, powder injection molding, spark plasma sintering, and liquid-phase sintering) and additive manufacturing (electron beam selective melting and laser powder bed fusion). Third, taking molybdenum disulfide as a representative, the layered crystal structure of molybdenum-based ceramic materials and their application potential and challenges in electronic devices, optoelectronic sensing, and biomedical detection are analyzed. Furthermore, this review proposes development strategies for the high-quality advancement of the molybdenum-based materials industry from three perspectives—precise alloy composition design, integrated innovation of advanced preparation processes, and industrialization of two-dimensional molybdenum-based materials—and provides an outlook on future trends. This review aims to offer systematic theoretical references for fundamental research, technological development, and engineering applications of molybdenum-based materials, thereby promoting the high-value-added utilization of molybdenum resources and the self-reliance of the industrial chain in China).

Abstract: Iron existed in the form of oxides and also, it is mostly abundant as well as the dominant resource of the Earth for the constrictive industries of the world. The iron ore mineralogy of iron is mainly concentrated as hematite, goethite and magnetite oxides minerals. Beside those oxides the siderite, illmenite and many other are common iron ores. The Lege Worke -Dasu blocks of iron found in the Northern and northwestern part of Ethiopian plateau. This research study holds the main objective of determining the mineralogical composition and mineral assemblage of the iron ore mineralization of the Lege Worke - Dasu blocks. The geological field work with lithological mapping, reflected microscope (ore) petrographic study, mineralogical study using (XRD), and geochemistry of major and other elements were the most applied methodologies for this study. The mineralogical study of the Lege Worke - Dasu iron mineralization result shows that the iron ore body samples were characterized in terms of their mineralogical composition. The outcome result indicates that the ore body consists mainly hematite and goethite iron ore minerals are the dominant compositions documented from the polished section and XRD result. The outcome results of analyzed chemistry and ore study from the polished section studies are shows that the layered (laminated) and pisolitic textures of hematite ore, goethite ore compositions are the main outcomes of this research study. In addition to those ore mineralogy kaolinite gangue, anatase minerals are common constituents including quartz as a gangue mineral. Major oxide analyses for systematically selected samples were characterized by SiO2, Al2O3 and Fe2O3 and others. The whole rock chemistry of iron ore and surrounding rock of Lege Worke - Dasu blocks of iron mineralization were used to determine the iron mechanism of the current research area.
