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…
I. Core Data Summary Item Current Status Trend & Analysis Market Price Germanium ingot prices remain elevated. Domestic spot prices have climbed steadily from ~8,900 RMB/kg in early 2024 to ~18,850 RMB/kg (data as of Nov 2024). Recent policy adjustments…
Abstract: Germanium (Ge) is one of the most critical infrared optical materials, offering exceptionally high transmittance and an ideal refractive index within the mid-wave (3-5 μm) and long-wave (8-12 μm) infrared atmospheric windows. The full realization of its optical potential is…
Abstract Indium, a critical rare metal, has emerged as a cornerstone material for overcoming current semiconductor bottlenecks due to the unique and tunable optoelectronic properties of its compounds (e.g., indium tin oxide (ITO), indium phosphide (InP), indium selenide (InSe), and…
Abstract Iridium (Ir), a quintessential platinum-group metal, boasts an exceptionally high melting point of 2446°C (some sources cite 2450°C) and a density of 22.652 g/cm³ (20°C), ranking among the densest naturally occurring metals. These extreme properties make it indispensable in high-temperature, corrosive, and high-stress environments:…
This week, China’s indium metal market surged past a key resistance level to reach a yearly high, driven by robust demand from photovoltaics (PV) and semiconductors. While bullish sentiment dominates, the market remains cautiously optimistic due to ongoing supply-demand tensions and macroeconomic uncertainties. 1. Key Data…
