I asked a similar question not long ago:

donkey32.proboards.com/thread/1696

I guess you could use it, but you'd need a lot more of it than, say, perlite or vermiculite.

I know it's been done. For example, this photo album shows scoria insulation around the burn tunnel:

They don't show what they used to insulate the heat riser though…
