Abstract From the Canadian patent

The invention concerns a preparation process for a magnesium-based nanocomposite and another element or compound known for absorbing hydrogen and being non-miscible upon grinding with magnesium or its hydride such as vanadium or nobium. According to this process magnesium or a magnesium-based compound known for absorbing hydrogen is subjected to hydrogenation with a view to producing the corresponding hydride in powder form. The resulting hydride powder is mixed with the other element or compound or a hydride of this other element or compound and the resulting mixture is subjected to intense mechanical grinding until the corresponding nanocomposite in hydride form is obtained. The …

Why it's free to use

  • Filed October 22, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 22, 2017.
