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…
Abstract Solder alloys are tin (Sn)-based metallic materials widely used in electronics assembly, automotive radiator sealing, and other applications. The most common formulation is tin-lead (Sn-Pb) solder (e.g., Sn63/Pb37, melting point 183°C), valued for its low melting point, excellent wettability, and electrical conductivity (resistivity ~12.6 μΩ·cm). Lead-free solders (e.g., Sn-Ag-Cu systems) incorporate silver (Ag)…
Abstract Selenium (Se), a nonmetallic element, exhibits significant differences in physicochemical properties and applications depending on its chemical forms (elemental selenium, selenides, selenates, etc.). Toxicity varies drastically among forms—selenite (SeO₃²⁻) is 10 times more toxic than selenides, requiring strict intake…
Shaoguan Yuntian Metals Abstract Among precious metal compounds, rhodium acetate (Rh(OAc)₃) may not be a household name, yet it serves as an indispensable “core player” in industries like chemicals, pharmaceuticals, and advanced materials. Whether in high-end organic synthesis or fine chemical production, rhodium acetate stands out as one…
Shaoguan Yuntian Metals Abstract In the fiberglass industry, it is well-known that platinum-rhodium (Pt-Rh) alloys are essential for bushing plates in glass fiber production. However, few realize that these precious metals gradually volatilize, detach, and become adsorbed by surrounding refractory castables during high-temperature operations. When…
