Description
Overview
Germanium, a brittle metalloid, is primarily extracted as a byproduct from zinc ores or coal ash through complex refining processes, ensuring high purity for specialized industrial uses. Valued for its unique transparency to infrared light and excellent semiconductor properties, germanium plays a critical role in advanced technologies, including infrared optics for thermal imaging, fiber optic systems, and high-performance electronics like transistors and solar cells. Its ability to enhance the efficiency of photovoltaic cells also makes it essential in the renewable energy sector. With growing demand for cutting-edge applications, germanium’s scarcity and recyclability highlight its importance as a sustainable and strategic material in the technology metals market.
