Industrial Germanium Scrap Recycling

Primary products from industrial germanium scrap recycling include: infrared optical devices, fiber optic communications, advanced process chips, satellite photovoltaic substrates, and lithium battery anode materials. DONGSHENG achieves over 96% recovery rate for precious metal germanium in industrial germanium scrap recycling. The scarcity of precious metal germanium ensures consistently stable industrial germanium scrap prices.

Where Does Purified Germanium Scrap Go After Recycling?

Germanium Scrap Recycled in Semiconductor & Optoelectronics

Infrared optical devices: Purified recycled germanium scrap manufactures infrared lenses and thermal imager lenses, irreplaceable due to germanium's high infrared transmittance (8-14μm band).

Fiber optic communications: Recycled germanium tetrachloride serves as fiber dopant, enhancing signal transmission efficiency.

Advanced process chips: Silicon-germanium alloys used in gate-all-around (GAA) transistor channels for 3nm/2nm processes.

Precious Metal Germanium in Aerospace & Energy

Satellite photovoltaic substrates: High-purity germanium monocrystals form radiation-resistant solar cell substrates with >30% conversion efficiency.

Lithium battery anode materials: Nano-germanium composite graphite boosts specific capacity (>1600mAh/g).

Industrial Germanium Scrap Recycling Technologies

Germanium recovery from e-waste: Recovers germanium from discarded phones and LCD screens via high-temperature smelting (>96% recovery rate).

Exhaust dust recovery: Wet dust collection from fiber optic factory exhaust enables germanium dust extraction for reuse.
