Since this question is still unanswered :
I've been trying to find a source of stearic acid to coat aluminium powder during the ball milling process, but I've had very little luck finding any.
It all appears to be sold on the internet, and after phoning around returned no results, I was wondering if anyone had purchased some in maybe a supermarket or other source used for candles etc? Could you use any hard waxy substance? I.e. wax, beeswax?
Thanks.
