Nitrotriazolone has been svnthesised and fullv characterised. This exolosive was found to exhibit ~ ~ self-binding properties forming pellets at different loads. The compression strength of these pellets were in the ranee 80-128 kef/cm2 under one to three tonne/cm2 load. Other oressable formulations containinz ---n~trotr~azolone have also been successfully prepared A composltlon comparable to composltlon B was also oreoared uslne n~trotr~a?olone and tr~n~trotolucne (60 40) h4echanlcal oropertlc? and insenslllvltb . .of this new composition were found to be superior.

Nitrotriazolone incorporated sheet explosives were prepared and evaluated with respect to their explosive characteristics as well as mechanical and thermal behavior. 1,3,5-Trinitro-1,3,5-triaza-cyclohexane (RDX)/Estane (85:15) composition (density, 1:23 g=cm 3 and tensile strength, 0.5 MPa) was taken as reference and the effect of replacement of RDX by nitrotriazolone to the extent of 5-25% was studied. Inclusion of nitrotriazolone led to a remarkable increase in density (1:23 ! 1:41 g=cm 3 ) and mechanical properties (tensile strength: 0:46 ! 1:08 MPa). The major finding was increase in velocity of detonation by about an average 700 m=s over the reference composition. Velocity of detonation realized ranged from 6800 to 6900 m=s for RDX/nitrotriazolone/ Estane compositions. As regards sensitivity, nitrotriazolone-based compositions were relatively less vulnerable to impact and friction stimuli. Shock sensitivity of RDX/nitrotriazolone/Estane composition was also found to be of the order of 98-110 kbar as against 77 kbar for reference. The armor protection capability of nitrotriazolone-based composition against shaped charge was found to be at par with the corresponding RDX-based sheet explosive. Thermal studies revealed that nitrotriazolone and RDX incorporated sheet explosives with Estane binder decomposed as a unified composite, despite their widely differing decomposition/ignition temperatures.
