Micron sized nickel powder starts to congeal as temperatures rise up to 1000C. Tubule surface treatments on the grains will ooze away and the grains will start to melt together. See page 77 of the reference. Conclusion: Rossi is making changes to his design and not telling us about them. ** Cheers: Axil On Mon, Jul 23, 2012 at 11:29 PM, Ron Clark <[email protected]> wrote: > I thought Rossi was using micron-sized particles.**** > > ** ** > > ** ** > > Ron **** > > ** ** > > *From:* Axil Axil [mailto:[email protected]] > *Sent:* Monday, July 23, 2012 8:09 PM > *To:* [email protected] > *Subject:* [Vo]:Re: [Vo]:Re: [Vo]:Re: [Vo]:Re: [Vo]:Re: [Vo]:1000°C E-CAT! > **** > > ** ** > > I don’t remember Rossi saying recently that he is still using nickel > nano-powder.
