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…
