Germanium (Ge), as a Group IV semiconductor, has attracted sustained attention in optoelectronics and high-frequency communications due to its compatibility with silicon processing, high carrier mobility, and strong near-infrared absorption. However, the transition from laboratory to industrialization faces multiple technical barriers…
Indium is a silver-white metal with a faint bluish tint, exceptionally soft, highly malleable, with a melting point of just 156.61°C, a boiling point of 2,060°C, and a density of 7.30 g As a globally scarce strategic resource, indium serves…
Introduction Iridium, the rarest and most chemically inert of the platinum group metals (PGMs), is a critical enabler of technologies that operate at the extremes of temperature, corrosion, and wear. From the crucibles that grow laser crystals to the anode…
IntroductionTin, the essential bonding agent in electronics, underpins the functionality of every circuit board, semiconductor, and connector. With nearly 50% of global tin consumption directed to solder production, the end-of-life electronics stream represents a rich “urban mine” of this strategic…
Abstract:As global demand for NdFeB permanent magnets accelerates across electric vehicles, wind energy, and robotics sectors, praseodymium-neodymium recycling from end-of-life magnets and manufacturing scrap has emerged as a strategic pillar of rare earth supply security. This white paper provides a…
