Abstract: | Electrochemical methods have been used to study hydrogen in vanadium, titanium and three binary magnesium alloy systems. These
materials are all sensitive to air and/or water, which prohibits the use of aqueous electrolytes. The measurements have involved
the use of alkali halide and lower temperature organic-anion molten salts saturated with an alkali hydride so that they conduct
charge by the transport of hydride ions, rather than protons. Alkali metals, or their alloys, can be used as indirect reference
electrodes for hydrogen in these electrolytes. |
