A composite powder has been prepared by ball milling a mixture of LiBH(4) and LiAlH(4) together with 3 mol.% TiF(3). The powder starts to decompose between 450 and 520 K and the weight loss reaches up to 7.2 wt.%. The formation of AlB(2) is clearly observed after desorption at 673 K for 4 h. It is also confirmed that dehydrogenated product can be hydrogenated to about 5.1 wt.% H(2) at 623 K for 6 h under 70 bar of hydrogen. (c) 2008 Acta Materialia Inc. Published by Elsevier Ltd.
