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)…
