Re: [Vo]: Rossi/Parkhomov reaction and the hydrogen anion
The added silica in the Parkhomov experiment is consistent with improving the fracture toughness of the tube. The silica addition acts to blunt the defects in the alumina and make the cracks that start at such a defect arrest before a significant crack propagation occurs. This is good old engineering of brittle materials--alumina--to, in effect, give them more ductility. If the temperature gets to high however, even silica loses strength and the beneficial effects of checking crack growth are lost. Other higher temperature materials to add to the alumina fabrication process may work better. A ductile metal might be better for example.

[Vo]: Rossi/Parkhomov reaction and the hydrogen anion
One of the final decomposition products in the fuel bearing LiAlH4 is LiH. LiH decomposes in the 900-1000ºC range to Li metal and hydrogen. Note that LiH is an *ionic hydride*. That means that the hydrogen has more or less permanently grabbed an electron from the Li, making it an H- anion inside the compound. Decomposition of LiH is reversible, and I suspect at high temperatures and at the Parkhomov hydrogen pressures, the LiH is still liquid. Since the SEM images of the fuel https://drive.google.com/folderview?id=0B5Pc25a4cOM2fllFSWpFNVJoUlIxbERhRTE2M2FTY0s3TU9sZ2FsVG5wMGdodlE2ZW1JMVEusp=sharing show the Li-Al-Ni-H metal engulfing the Ni foam sintered webs, at 1000ºC, this metal alloy was liquid and was supplying - wait for it - hydrogen anions directly to the surface of the Ni. Hmmm, sounds like Piantelli's patent. Piantelli implicated the H- ion on the surface of the Ni in LENR. Bob Higgins
