A composite powder has been prepared by ball milling a mixture of LiBH4 and LiAlH4 together with 3 mol.% TiF3. The powder starts to decompose between 450 and 520 K and the weight loss reaches up to 7.2 wt.%. The formation of AlB2 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.
