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:…
