AbstractRuthenium is an important platinum group precious metal catalyst, and its powder particle size (typically at the nanoscale) is a key determinant of its catalytic performance. Changes in particle size profoundly influence catalyst activity, selectivity, and stability by altering the…
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…
