Germanium metal is primarily used for the production of infrared and specialty optical lenses, but is also used in semiconductors and solar cells. Polycrystalline ingots are produced via a zone refining method that involves raw materials being melted and purified as they pass through a tube. High purity ingots of 99.999% purity or higher are then cut as they exit.
The world's largest producer of refined germanium is China, which accounts for about 70 percent of the over 150 metric tonnes produced worldwide each year. Other major producing countries include Russia and Canada.
SMI Ltd. is a supplier of various sizes of polycrystalline germanium metal. Please feel free to contact us regarding your specific requirements, to purchase germanium or to inquire regarding the current price of germanium metal ingots.
