文摘
Niobium and tantalum are rare refractory metals of large industrial value. Their reserves belong to “critical-raw materials, which leads to the necessity of evaluating the risks associated with the presence of primary and technogeneous raw-material sources of niobium and tantalum and with the influence of these factors on the offer and demand for these metals and their compounds, allowing for traditional and new application fields. World reserves of niobium and tantalum are analyzed and the dynamics of varying the structure of raw materials base and production solutions implemented and proposed for their processing is considered. A modern market of niobium- and tantalum-based materials is described, the main players on this market are noted, and tendencies in varying the structure of consumption of functional materials based on these metals is considered.
