It could well be powdered mica.  One use of powdered mica is as a case
lubricant when reloading cartridges.

Years ago Motorola sold a powder lubricant for slug
tuned coils.  Of course all of their two-way equipment
was full of slug tuned coils.

I still have some of this around "somewhere"!  It was
white in color and very fine and very "slippery".  I
am not sure exactly what it was made from, maybe
finely powdered teflon.

It definitely worked and at least over several years
did not "gum up" or otherwise keep the slug from being
able to be tuned.

out the hard way, hi.
