Potassiumchlorate Posted December 30, 2011 Share Posted December 30, 2011 I dry mine for three hours in 225-250oC. Then I mill it with +1% SiO2 for one hour and put it in airtight glass jars. There are some comps where you need the anhydrate form, and besides my strontium nitrate is a bit coarse. Link to comment Share on other sites More sharing options...
