1 Οκτ 2024 · The importance of niobium as an MAE is underscored by its ability to enhance material properties such as high heat and corrosion resistance, increased strength, reduced density, exceptional conductivity, and enhanced biocompatibility (da Silva Lima et al., 2022; Dolganova et al., 2020; McCaffrey et al., 2023).
From its use in aerospace technology to medical implants, the versatility and durability of niobium continue to offer boundless possibilities in scientific and industrial applications. Its relative rarity and unique characteristics make it not only an element of interest but also of great value.
Recent developments demonstrate niobium oxide used in lithium-ion battery technologies can increase energy storage to significantly improve the range and performance of electric vehicles, and also reduce the risk of short circuits and fires by limiting lithium metal formation.
Metallothermic Reduction: Initially, niobium metal was produced by PM methods, which involved high-temperature vacuum sintering and carbon reduction. However, in the early 1960s, aluminothermic reduction and electron beam purification came into general use.
Niobium is a versatile player that adds value by improving material properties. When added to materials like steel, glass, and aluminum castings, Niobium makes them smarter and helps to lower environmental impact, while also delivering other benefits like better performance, improved safety, and increased value.
Niobium, also known as columbium, is a metal mainly used as a microalloying element in specialty steel. It is utilized in superalloys for heat-resisting equipment, jet engine components, and rocket subassemblies to strengthen the alloy at high service temperatures.
Niobium consumption is dominated by its use as additive to high strength low alloy steel and stainless steel for oil and gas pipelines, car and truck bodies, architectural requirements, tool steels, ships hulls, railroad tracks.
