Article of interest: new melt-castable explosive

The compound is bis(1,2,4-oxadiazole)bis(methylene) dinitrate. I don't think it will replace TNT anytime soon, but it's still interesting.

Original research article:

Discussed herein is the synthesis of bis(1,2,4-oxadiazole)bis(methylene) dinitrate, determination of its crystal structure by X-ray diffractometry, calculations of its explosive performance, and sensitivity measurements. Steps taken to optimize the synthesis process and to improve yields of the dinitrate are also discussed. Bis(1,2,4-oxadiazole)bis(methylene) dinitrate has a calculated detonation pressure 50% higher than that of TNT. The dinitrate compound exhibits a relatively high decomposition temperature that is rarely observed for nitrate-based compounds. The dinitrate was found to have lower sensitivities to impact and friction compared with RDX. It is believed that intramolecular hydrogen bonding observed in the crystal lattice assists in the relatively high thermal stability and relatively low sensitivity of the material.

As below, so above.

Thanks for the share. It is also interesting that its a bit of a gap in the market, a good melt castable explosive that isn't TNT. I suppose plastic explosives have been all the rage.

Also, the news site made a bit of a blunder I thought was hilarious, there was just too much science coming out in one day for some poor editor
