I have checked in to a few things and have found that super fine dimond powder is not that expencive. I have been thinking about using it in some sort of thermal past. How ever i have no idea on what to use to suspent the dimond dust in. Also some people have expresed concern about the abracive nature of dimonds. I think that if some one put the dust in to a drum and slowly spun it for some time the dimonds would dull any abracive edges and more or less ball the particles. Any one have any thing to add to this???
