Niobium-based oxides have drawn increasing interests as a potential choice of anode materials with high safety and fast energy storage kinetics. This review discusses and summarizes the recent progress and challenges of binary and ternary niobium-based oxides for fast energy storage techniques. The ...
Niobium-based alloys find applications in various industries due to their unique properties. They are commonly used in aerospace and aviation industries for manufacturing superalloys, which are heat-resistant and can withstand high-stress environments, such as jet engines and gas turbines. Niobium alloys...
Refined niobium-based ferroalloys are provided by removing lead and other impurities therefrom by a process comprising charging niobium ore concentrate and/or niobium oxide or a mixture of niobium oxides to a metallothermic reaction chamber, admixing the ore concentrate and/or niobium oxide with a ...
In pursuit of this goal, one branch of LIBs' anode research has focused on niobium oxide-based materials, which allow rapid lithium transport within their crystal structures. Although several review articles have offered an overview of the development of niobium oxide-based anode materials, a ...

This contribution focusses on the use of Nb-based materials for the preparation of hybrid nickel-semiconductor electrodes for use in the electrochemical generation of hydrogen. The Nb-based semiconductors (i.e., Nb2O5 and Nb-3(PO4)(5) show good performance for the H-2 evolution reaction (...
Recently, niobium (Nb)-based oxides with insertion-type Li storage mechanism are considered of great potential as alternative high-rate anode materials [18]. First, the operating potential of most Nb-based oxides are in a range of 1.0–2.0 V (vs. Li+/Li) involving redox reactions of Nb5...
niobium-based alloyswettingThe results of investigations of wetting of Al2O3, ZrO2, AlN, VK94-2, and porcelain using various niobium-containing alloys are presented. A method for brazing ceramic materials with niobium by the contact-reactive methods through nickel and also the conditions of ...
We report a novel method for the fabrication of superconducting nanodevices based on niobium. The well-known difficulties of lithographic patterning of high-quality niobium are overcome by replacing the usual organic resist mask by a metallic one. The quality of the fabrication procedure is demonstrate...
