AbstractRhenium, the last naturally occurring stable element to be discovered and an extremely rare dispersed metal, has become an indispensable critical material for modern high-performance aerospace engines due to its high melting point of 3180°C and exceptional high-temperature strength and…
Abstract: Gallium is a rare and dispersed metal that rarely exists as an independent mineral. It is primarily recovered as a by-product from bauxite, zinc ores, and coal fly ash. Core industrial extraction processes include amalgam electrolysis, ion exchange, solvent extraction,…
Introduction Hafnium (Hf), a rare high-melting-point metal, exhibits irreplaceable value in high-tech industries due to its unique nuclear properties, exceptional thermal stability, and superior corrosion resistance. By alloying with other metals, hafnium’s performance can be precisely tailored to meet extreme…
In recent years, industrial discourse has centered on display advancements, AI computing power, and new energy technologies. However, behind these rapidly evolving landscapes, a critical yet often overlooked question emerges: Can the long-term stability of key material supplies keep pace…
AbstractAs a critical rare earth functional material, the purity of metallic dysprosium directly determines the performance of cutting-edge products such as NdFeB permanent magnets and magnetostrictive alloys. The scientific identification of dysprosium purity is primarily based on national and industry…
