网页2020年9月24日 · Niobium is used for alloying non-ferrous metals. In ferrous metallurgy, niobium is widely used in the form of ferroniobium for microalloying structural steels, low-alloy pipe steels for main oil pipelines, and chromium–nickel stainless steels to prevent intercrystalline corrosion.
网页2024年6月1日 · ferroniobium: electro-carbothermic process, electro-silicothermic process, and metallothermic process. The raw materials of ferroniobium pro-duction include industrial niobium pentoxide, niobium concentrate, tantalum extraction slag, etc. In the electro-carbothermic process, carbon is used as the reductant, and the high-carbon
Niobium: The unseen element - A comprehensive ... - ScienceDirect
网页Niobium, a critical but often overlooked material, plays a crucial role in the Anthropocene era. Serving as a microalloying element in steel, typically at concentrations of 0.05–0.15 wt.%, niobium significantly enhances steel properties.
网页Ferroniobium is an important iron-niobium alloy, with a niobium content of 60-70%. It is the main source for niobium alloying of HSLA steel and covers more than 80% of the worldwide niobium production. The niobium is mined from pyrochlore deposits and is subsequently transformed into the niobium pentoxide Nb2O5.
