Write short notes on Metallic Hydrides. |
| Answer» Solution :Metallic (Interstitial) Hydride: Metalic hydrides usually obtained by hydrogenation of METALS and alloys inwhich hydrogen occupies the interstitial ites (voids). Hence, they are called interstitial hydrides. These hydrides SHOW properties similar to parent metals and hence they are also know as metallic hydries. Most of the hydries are non-stoichiometric with variable compositon `(TiH_(1.5-1.8)" and "PdH_(0.6-0.8)`, some are relatively LIGHT, inexpensive and THERMALLY unstable which MAKES them useful for hydrogen storage applications. | |
