1. I’ve done this reaction before, although with ammonium nitrate instead of potassium nitrate. It’s not very exothermic and is pretty straight
forward and safe. I didn’t get a very high yield though.
2. Urea nitrate can be detonated on its own, but I would suggest mixing with ammonium nitrate to make an oxygen balanced explosive. I’ve tested this
mixture, and it’s cap sensitive and fairly powerful.
3. While nitrourea is said to be more powerful, I’ve heard it has poor stability. Nitroguanidine is more powerful and stable.
4. I don’t know.
5. I successfully detonated a charge of AN/UN with a diameter of 1cm.
6. Urea nitrate is very insensitive, don’t know about nitrourea.
If you’re trying to make shaped charges, pure urea nitrate is not a good choice. It has a low detonation velocity. A mixture of urea nitrate and ETN
could work. You wouldn’t have to make nearly as much ETN.
