I like where this is going, in addition to Jones’ suggestion
[snip] Why not start with nano-powder - compress it mildly and heat to
the level of diffusion bonding, and thereby forget about leaching?
My first concern is that the the remaining pores might not be as small as
we want; however, high-quality mateirials with no spaces (very few) have
produced in high-vacuums.---We could mix two sets of nano-particles together
and leach, as before; this would give us more control over cavity shaps and
sizes. But this means we are still looking for materials with a low heat of
fusion---
OR If we can mix our materials as a powder then simply melt them in a ceramics
kiln---???
How about mixing the hydrogen with an inert gas and then circulating
it through your powder so we limit the potential for combustion even if
the powder reaches pyrophoric dimensions? You would want to flush an inert gas
through the powder to get rid of oxygen, then flushPure Hydrogen through it.
The goal is
to find a self assembly method with powder that avoids the huge milling
costs involved with the Haisch Moddel prototype. Can you send a link to
this?H-M are limited to the 100nm mechanical limit for milling so their
Particle sizes only matter from the standpoint of providing lots of surface
area for lots of Cavities to be formed. Cavity sizes are extremely important.
100 nm cavities are literally 10,000 in the Casimir Effect as 10 nm.
