Molten Lithium Hydride is almost the Most Powerful Reducing Agent

A few years ago Tom (ExF) and I did a collaboration and he showed the spontaneous combustion of silane and diborane. I went further and in this video I'll show you in addition to silane and diborane also phosphine, titanium tetrahydride and possibly stibine and stannane. I cannot confirm the formation of the last two gases so see for yourself and leave comments.

My favorite reaction uses an isotopic sister-compound of LiH: LiD (Lithium deuteride). First all, some neutrons are required: ⁶LiD + ¹n → D + T + ⁴He↑. Then, we need 63keV to form D + T → ¹n + 17.6 MeV + ⁴He. I really love this reaction.

[@drMentalBar]

And now we've got thermonuclear... 😂

[@debrainwasher]

@@drMentalBar It always depends on your intention. Since the difference between an explosive device and a power plant is only defined by the energy turnover by time unit, you can use this reaction for electrical power production as well. One feasible way is to use LiD as a fuel in a high yield, high pressure pulse plasma fusion reactor, we had developed in our institue about ten years ago - before it was shut down by our government due to issues with our oil industry and mineral oil tax system: First, kick-start the reaction by exploding a tiny amount of LiD in the Hohlraum within a T-gas atmosphere. This will create a bunch of 14.1MeV-neutrons, that produces additional T from LiD in situ for subsequent shots. Thermal power can be extracted from moderated surplus-neutrons and Alpha-particles, inductively slowed down (provides about 20% of the total output power as electricity). Since each cycle is 100% externally powered, all hassles with the Lawson criterion vanish and you can get a yield, Tokamak-people can only dream of. After we had started with the aneutronic p-B-reaction scheme, politicians freaked out. Pulse plasma fusion science at SNL (Sandia National Lab) was defunded by the US-government and the institute for nuclear energy physics at the University of Basel (Switzerland) was completely closed down. Since 2017, our nuclear law forbids exothermic nuclear fusion for power generation explicitly.

Smaller molecule size, the only thing that can reduce this compound is theoretical metallic hydrogen and it should reduce to more metallic hydrogen, that's why obtaining even a single sample of metallic hydrogen is important.

According to wikipedia, TiH4 is thermodynamically unstable and has never been produced in bulk. Not sure what product you made, but at those temperatures, there's no way TiH4 survived long enough to exit the tube. Also, all the halides you mention would flash boil on contact with the ~700C liquid hydride, so this whole video is suspicious.
