Abstract

As an energetic material of great interest,the work capacity of dihydroxylammonium 5,5'-bistetrazole-1,1'-diolate(TKX-50)has been questioned recently.Although some research groups have explored the reasons for the low working ability of TKX-50,the plane impact experiment on powdered TKX-50 is obviously closer to the practical application,and the conclusions based on this are more guiding.Hence,we performed shock Hugoniot measurements of powdered TKX-50 between 5.65 and 16.29 GPa.The plane impact experiments of powdered TKX-50 were carried out and the shocked Raman spectra were collected.By Raman spectroscopy analysis,a new peak of powdered TKX-50 was found between 19.47 GPa and 24.96 GPa,which may be caused by decomposition/phase transition and was related with the low work capacity.
