The location of Ti containing phases after the completion of the NaAlH4+xTiCl3 milling process

The NaAlH 4 + x TiCl 3 ( x 4 mosaic size (coherence length) determined from the X-ray synchrotron diffraction lineshape, and measurement of the external powder grain dimensions of ca. 250–300 particles by TEM, reveals that after the completion of the milling process, 〈1 1 0〉 {1 1 1} edge dislocated 2–20 nm Al crystallites are dispersed in a Ti rich amorphous (a-)Al 1− x Ti x (0.3 x 50 Ti 50 composite is embedded on the surface of single crystalline NaAlH 4 powder grains. The NaAlH 4 single crystal powder grains are moderately defected with uncorrelated defects, induced from the milling process.
