There are a variety of suppliers for the amateur rocketry experimenter. The list below is some of the suppliers known to CP Technologies, but it is not an all inclusive list. Ebay and Amazon are also a source for chemicals and other items.

Ammonium nitrate is often available from the list below, but if you can't find it there, search suppliers of exploding targets. They often carry it in the form of tiny prills that you can grind into a powder. Any grinder with a chopping type blade action (Simple blender) or hammer mill action will work. A simple ball mill will work as well. Grinding wheel type grinders will not work well as the ammonium nitrate tends to coat the grinding wheel and prevent it from working.

One final tip, chemicals will become scarce as the 4th of July approaches since amateur pyro guys starting making their fireworks for the holiday. Suppliers will often be out of stock in June and July and just starting to get inventory back in their stores in August. Your best time to buy is in the winter. Buy all the chemicals you will need for your rocket motors at that time so you will not run out during the summer flying season.
