Lithium at that pressure will not boil at the temperatures being used. If you read Langmuir's work, you will see that it takes over 2500C for any significant hydrogen molecule dissociation, and it would be much hotter still to get a hydrogen plasma. > >>> Rossi says that his nickel is 5 9s pure. >>> >> 5 9's pure has no bearing on whether the Ni was dissolving.

There was no explosion in the Lugano experiment. Also, from personal experience, when Ni is heated in H2, it is fully oxide free by 250C and by 300C the sintering of the particles begins. This happens long before there was ever an explosion. Not only that, but after the explosion, the Ni core was a completely intact molded rod of sintered material. If you look at the micrographs, it would be impossible to create the sintered 3D web structure found by "melting" of the Ni. > >>> >>>> If the small features of the Ni are not complicit in the LENR, then it >>>> is not clear that size of the starting particles mean very much. >>>> >>> >>> Where is reference to this? >>> >> The reference is the Lugano report and Ed Storms' micrographs of >> the MFMP ash.

However, the carbonyl Ni particles by themselves don't want to sinter easily into a solid block - they want to sinter into a porous body naturally. > > >> The Ni particles get reduced of their oxide easily by 300C and they begin >>>> sintering into a porous web long before the reaction begins.

Of course the Ni ash will also be collected for examination. This, plus the existing papers on LiAlH4 decomposition will go a long way in understanding what is going on. I will be able to stop the experiment at any point and gather the gas and analyze the ash.
