ENERGETIC HIGH PRESSURE POLYMORPH OF CROCONIC ACID AND HIGH ENERGY COMPOSITIONS FORMED THEREFROM
Provided is a high pressure polymorph of croconic acid. The high pressure polymorph of croconic acid has an unexpectedly high energy release and is suitable for use in detonable compositions. The high pressure polymorph of croconic acid is recoverable to ambient conditions and exhibits only a modest increase in density but a greatly improved energy release.
