Abstract Gallium’s core advantages in the semiconductor industry stem from the unique physical properties of its compounds—such as gallium arsenide (GaAs) and gallium nitride (GaN)—including high electron mobility, wide bandgap structures, and high-temperature stability. China’s leadership in gallium refining and recycling technologies provides critical support to…
Abstract Hafnium (Hf) and zirconium (Zr), both Group IVB transition metals, share similar chemical properties. However, hafnium’s thermal neutron capture cross-section is significantly higher than zirconium’s (~600 times), leading to distinct roles in nuclear applications. These elements coexist in nature, primarily…
Abstract The extraction and purification of osmium (Os) primarily rely on oxidative distillation, combined with chemical reduction techniques such as sodium sulfide precipitation, ammonium chloride precipitation, and formic acid reduction. To preferentially separate osmium from platinum group metal (PGM) concentrates, sodium peroxide fusion…
Abstract Tellurium, as a rare and dispersed metal, holds significant value across multiple industrial sectors. Its primary applications include: CdTe solar cells, known for their low-light performance and high conversion efficiency, represent a major direction in photovoltaic technology. Meanwhile, bismuth…
Abstract The price volatility of dysprosium (Dy) is primarily influenced by multiple factors, including supply-demand dynamics, policy regulations, international competition, and industrial chain restructuring. Recently, the price of dysprosium oxide (Dy₂O₃) plummeted by 7,500 yuan per ton in a single day (reaching 1.4075…
Abstract In the growth of germanium single crystals, critical process parameters include growth temperature, growth pressure, growth rate, and the relative positioning between seed crystal and melt. Optimizing these parameters—such as employing vertical growth methods and precise temperature control—effectively reduces…
Abstract The environmental advantages of indium recycling primarily lie in reducing pressure on resource extraction, lowering energy consumption, and promoting a circular economy. Recovering indium from waste electronic products, such as ITO (indium tin oxide) targets, significantly decreases environmental pollution…
Abstract Tin is an important metal with favorable physical and chemical properties, widely applied across multiple industrial sectors. Its primary uses include the manufacture of alloy materials such as bronze and solder, extensively employed in electronic packaging and welding. Tin…
Abstract Selenium is an important chemical element widely utilized across various industrial sectors. Its primary applications include photosensitive materials in the electronics and electrical industries, decolorizing agents in glass manufacturing, and additives in the metallurgical industry. Selenium is also employed…
Abstract The extraction and separation processes of terbium play a vital role in the processing of rare earth resources and are widely applied in high-tech fields.
