Unfortunately, the solubility of alkali metals in liquid ammonia isn't
that impressive -- the lithium-ammonia solutions are still mostly ammonia.
They're cute (in fact they're weird), but for rocketry they seem to give
you the worst of all worlds: aggressive enough that they might well cause
trouble for things like seals, probably not aggressive enough to be
reliably hypergolic with LOX, and liquid ammonia is a bit of a pain and
notoriously hard to burn well.
