Electrodeposition of indium from trihexyl(tetradecyl)phosphonium chloride
The high thermal stability of Cyphos IL 101 allowed SIM² KU Leuven researchers to investigate the electrochemical behavior of indium at temperatures between 100 °C and 180 °C. The electrochemical deposition of indium followed a two-step process. The work was published in Green Chemistry.

Rare-earths permanent magnets were treated with solvometallurgical solutions of Br2 in organic solvents to remove the Ni-Cu-Ni coating prior to direct recycling. A comparison with 2 M HNO3 treatment proved the advantages of the solvometallurgical process.

Germanium is a precious metal which is mainly used as a semiconductor in electronics and infrared optic industries, and as a polymerisation catalyst for the production of polyethylene terephthalate. Due to its high supply risk and its high economic importance, germanium is considered as one of Europe’s critical metals
