Hello, I'm new here and my English is not very well. Sorry for any mistakes.
Rossi mentioned nickel-62 and nickel-64 isotope enrichment in an
interview and in his patent
http://www.google.com/patents?id=84vwAAAAEBAJ&zoom=4&dq=rossi%20nickel%20hydrogen&pg=PA1#v=onepage&q&f=false
prepared powder seems to be contaminated by traces of Zn. I think there
is a cheap and purely chemical way to reach the result. Starting with
nickel carbonyl
http://en.wikipedia.org/wiki/Tetracarbonylnickel
and centrifuging it at near room temperature we can easily get the
desired isotopes. After that carbonyl can be oxidised to nickel chloride
and the product can be used for preparing of Urushibara catalyst
http://www.erowid.org/archive/rhodium/chemistry/urushibara.html
via mixing solution of nickel chloride with zinc dust and following all
necessary steps. This catalyst powder can be dried out in high vacuum
and filled with hydrogen gas. It must have less impurities than any
nickel powder made in contact with atmosphere and very irregular large
surface.
Nickel carbonyl and chlorine are highly toxic, but compared to other
procedures this one can be done in scalable mode without Arata-like high
tech equipment. So may be Rossi have followed a close route.
