TL;DR: A less sensitive explosive, 3-nitro-1,2,4-triazol-5-one (NTO) has a crystal density of 1.93 g/cm 3 and calculated detonation velocity and pressure equivalent to those of RDX as discussed by the authors.
Abstract: A less sensitive explosive, 3-nitro-1,2,4-triazol-5-one. The compound 3-nitro-1,2,4-triazol-5-one (NTO) has a crystal density of 1.93 g/cm 3 and calculated detonation velocity and pressure equivalent to those of RDX. It can be prepared in high yield from inexpensive starting materials in a safe synthesis. Results from initial small-scale sensitivity tests indicate that NTO is less sensitive than RDX and HMX in all respects. A 4.13 cm diameter, unconfined plate-dent test at 92% of crystal density gave the detonation pressure predicted for NTO by the BKW calculation.

TL;DR: In this article, a comparison of desensitivation of PBX either by TATB or by NTO has been made, and the sensitivity levels were found equivalent while the detonation velocity of the NTO based PBX was slightly higher.
Abstract: Looking for explosives for Low Vulnerability Ammunitions leads to an interest in explosive molecules less sensitive than the usual nitramines (RDX, HMX). If TATB is quite convenient in terms of sensitivity, its performance is too low. The researches described here are related to synthesis and use of NTO (nitrotriazolone), another insensitive molecule. The synthesis by nitration of TO (triazolone) is easy and the two steps from available starting materials have been optimized. A comparison of desensitivation of PBX either by TATB or by NTO have been made. The sensitivity levels were found equivalent while the detonation velocity of the NTO based PBX was slightly higher. Unfortunately in this case, the failure diameter would be larger. The last part relates to an extensive characterization in terms of performance and vulnerability to fast cook off, slow cook off, bullet impact, shock sensitivity and sympathetic detonation of a NTO and HMX based PBX. This PBX, B 2214, was one of the first examples of explosive composition showing no sympathetic detonation, even in 248 mm large diameter.

TL;DR: In this paper, the authors synthesized and fully characterised the self-binding properties of nitrotriazolone and trinitrotoluene and found that the compression strength of these pellets were in the range 80-128 kgf/cm2 under one to three tonne/cm 2 load.
Abstract: Nitrotriazolone has been synthesised and fully characterised. This explosive was found to exhibit self-binding properties forming pellets at different loads. The compression strength of these pellets were in the range 80-128 kgf/cm2 under one to three tonne/cm2 load. Other pressable formulations containing nitrotriazolone have also been successfully prepared. A composition comparable to composition B was also prepared using nitrotriazolone and trinitrotoluene (60:40). Mechanical properties and insensitivity of this new composition were found to be superior.

TL;DR: In this article, the thermal decomposition characteristics of explosives CL-20 and NTO were studied using thermal analytical techniques (TG, DSC), then the compatibility of above two explosives with silicone rubber, and the decomposition kinetic parameters such as activation energies of decomposition, the frequency factor of the decompose reaction are also evaluated by non-isothermal DSC techniques.
Abstract: The new polycyclic nitramine 2,4,6,8,10,12-hexanitrohexaazaisowurtzitane (HNIW) has been focused as a considerable amount of research recently on investigating its polymorphs, relative stability, and respective reaction chemistry. It is known as CL-20 popularly, CL-20 is a very high-energy and relatively high oxygen balance value crystalline compound whose method of synthesis and detailed performance data are still classified. 5-oxo-3-nitro-1,2,4-triazole (NTO, or nitrotriazolone) was an insensitive molecule comparison general explosives, and the NTO based polymer bonded explosives (PBX) was a low vulnerability explosive. Both energetic materials are all very important high explosives, which is used in a variety of military formulations widely owing to the properties of high energy and desensitization of PBX, many researchers have demonstrated the usefulness of above two energetic materials in explosive component. In this work, the thermal decomposition characteristics of explosives CL-20 and NTO were studied using thermal analytical techniques (TG, DSC), then the compatibility of above two explosives with silicone rubber, and the decomposition kinetic parameters such as activation energies of decomposition, the frequency factor of the decompose reaction are also evaluated by non-isothermal DSC techniques.

TL;DR: The chemical formula and molecular structure of AZTO indicate that it may be effective as an insensitive explosive, and the process may therefore present an efficient and productive remediation method for wastewater from NTO manufacture.
