Tellurium can also be refined by electrolytic reduction of sodium telluride.
2.
Electrolytic reduction allows the production of metals and metal alloys in sub = �m-thick layers.
3.
Once the ore is mined, the metals must be extracted, usually by chemical or electrolytic reduction.
4.
It has been reported that this method provides a 40 % reduction in cost per pound over the electrolytic reduction method.
5.
This can be accomplished through chemical means such as smelting or through electrolytic reduction, as in the case of aluminium.
6.
Julius Tafel discovered that hydroxylamine hydrochloride or sulfate salts can be produced by electrolytic reduction of nitric acid with H 2 SO 4 respectively:
7.
Aluminium is extracted by dissolving its oxide Al 2 O 3 in molten cryolite Na 3 AlF 6 and then by high temperature electrolytic reduction.
8.
A new process, solid oxide membrane technology, involves the electrolytic reduction of MgO . At the cathode, ion is reduced by two electrons to magnesium metal.
9.
The other main mechanism involves the electrolytic reduction of ionised hydrogen on the surface of the metal lattice, also followed by the diffusion of the protons into the lattice.
