A Process for the Recovery of Gallium from Gallium ...

The recovery of gallium (Ga) from gallium arsenide (GaAs) scrap using a leaching-ion exchange method was investigated. The ground GaAs scrap was leached, using 2.0 N nitric acid at 30 °C for 1.0 h, and the dissolution of Ga and arsenic (As) reached 98%. The pregnant solution with a 1/20 dilution ratio was then passed through a weak acid chelating resin Diaion CR-11.

Advantages and disadvantages of GaAs solar cells

2021-9-8 · Gallium arsenide is more brittle than silicon in physical properties, which makes it easier to break when processed. Therefore, it is common practice to make it into a film and use a substrate (often Ge[Germanium]). To counter its disadvantages in this respect, but also increase the complexity of the technology. The process of thin-film battery ...
