I couldn''t buy it locally, and why bother when I could make my own. In order to obtain a good quality powder, you''ll need a ball mill (among other things). I designed mine based on Dan Williams'' information and it worked great. The heart of the mill is the motor. I used a ½ hp 1725rpm 115v motor that I found on e-bay.
