One attractive feature of alanates is that lithium and sodium salts are readily available commercially. Magnesium alanate can be readily prepared with sodium alanate and magnesium hydride via a metathesis reaction. The mixed metal alanate, Na2LiAlH6, is prepared through ball milling of sodium hydride, lithium hydride, and sodium alanate. Potassium alanate can be prepared by the direct synthesis of potassium hydride and aluminum under high temperature and pressure.  [Pg.382]

It is noteworthy that variations in the crystal structures of MAIH4 compounds (M = Li, Na, K) arise from the differences in the size of the alkali cations of LL, Na, and K, which result in coordination numbers of 5, 8, and 10, respectively. [Pg.385]

Recently, metal-doped aluminium hydrides have been proposed as further potential hydrogen storage materials [107, 123]. Among lightweight metal hydrides the lithium and sodium alanates (NaAfflU, LiAlH4) have been widely... [Pg.62]

It can be summarized that of all the complex aluminum hydrides presented in this chapter only NaAlH4 up till now partially fulfils the requirements for a storage material for mobile fuel cell applications. Over the last decade, the kinetics as well as the cycle stability of doped sodium alanates has been improved. Nevertheless, for application in a low-temperature fuel cell the storage capacity seems to be too low because only the first decomposition step (3.6 wt.% hydrogen) can be used. [Pg.150]
