Urea Perchlorate
This material looks interesting but it seems to have limited data about its explosive properties as a unit.I have seen its synthesis and formulation with binary explosives in the patent file.It looks to improve nitromethane and other nitroalkane binaries better than with AN.According to the US patent#3,952,655 which states:
(A) Synthesis of Urea Perchlorate
606 Grams of urea were added to 1040 g of 35% hydrochloric acid and dissolved therein under agitation. Then, 1405 g of sodium perchlorate were added to the solution and the mixture was stirred vigorously for 10 minutes at 40.degree.C and cooled to 20.degree.C. The precipitated crystals were separated by filtration. These crystals were sodium chloride. The filtrate contained about 65% of urea perchlorate but still contained a small amount of sodium chloride dissolved therein. Thus, the filtrate was concentrated under reduced pressure at a temperature below 80.degree.C and filtered while hot, thereby removing the majority of the sodium chloride. By repeating this procedure comprising concentration and cooling for the aqueous solution of urea perchlorate thus obtained, crystals of urea perchlorate could be produced in a high yield.
The urea perchlorate prepared in this manner is a colorless crystal in the form of thin plates with a melting point of 82.degree.C and a solubility in 100 parts of water of 950 parts at 20.degree.C.

Guys do you have additional explosive information about this promising material?
