“…Compatibility studies of DBX‐1 with a variety of output powders, bridgewire materials and component metals were conducted by both metal coupon and DSC test methods 21, 22. Metal coupon testing was done by putting a small sample of DBX‐1 powder in contact with the coupon and placing the coupon in a humidity chamber at 93 % RH (saturated potassium nitrate) at ambient temperature (18–25 °C).…”

Efforts directed towards creating new environmentally friendly replacements for existing primary explosives have resulted in development of copper(I) 5‐nitrotetrazolate (DBX‐1). The chemical and physical properties of this material have been extensively investigated and it appears that DBX‐1 is a suitable drop‐in replacement for lead azide in a variety of ordnance applications. DBX‐1 is easily prepared, has excellent thermal stability and has safety and performance properties which are equivalent to or exceed those for lead azide. A program to qualify DBX‐1 for military use per NAVSEAINST 8020.5C has recently been completed and data has been forwarded to NSWC‐IH for submission to Naval Sea Systems Command.

Desensitisation of explosive materials using polymers is an important area in safe utilisation of explosives in various applications. The RDX/viton composition has been developed using co-precipitation method with varying content of viton, ranging from 5 to 35 wt per cent. RDX and viton were dissolved in acetone which is a common solvent for RDX and viton, and then the acetone was extracted from the solution by distillation resulting in homogeneous RDX/viton composition. Infrared spectroscopy studies indicated presence of RDX and viton in the resulting compositions. Thermogravimetric and differential thermal analysis studies made on yielded compositions confirmed that RDX is present in the composition in desired content. The shift in exotherm of RDX/viton composition as compared to RDX showed that polymer-bonded RDX compositions are more stable. The impact sensitivity studies showed that sensitivity of RDX/viton composition decreased with increasing content of viton. The similar trend was observed for friction sensitivity. The co-precipitation method has been found to be advantages to obtain homogeneous composition of RDX and viton (with viton content up to 25 wt per cent) as revealed by linear trend in sensitivity data measurements. It has been demonstrated that the sensitivity of RDX can be tailored within a wide range using viton so as to suit in desired applications.Defence Science Journal, Vol. 65, No. 4, July 2015, pp. 287-291, DOI: http://dx.doi.org/10.14429/dsj.65.8647

“…Higher sample size increases the possibility of physical contact in between the materials tested, and ensures the reliability. On the other hand, the foremost advantages of using DSC and TGA methods are to make experiments quicker and safer . However, TGA and DSC methods are suitable for the testing of primary explosives and pyrotechnics, their applicability for propellants, and PBX can be questioned.…”

Mechanical, thermal, and sensitivity properties of plastic bonded explosives (PBX) depend on the type of ingredients in their formulation. Aim of the work is to develop aluminized cast PBX formulations and process conditions by using alternative inert plasticizers to have similar or better properties than PBXN‐109 without compromising sensitivity properties. Although very small portion of total production of plasticizers is used for solid rocket propellant and explosive formulations, they play very significant role in that area. Both inert and energetic plasticizers have involved propellant and explosive formulations to improve process parameters, mechanical properties, and even insensitivity properties of them. Isodecyl pelargonate and dioctyl adipate are the most preferred inert plasticizers in polyurethane based thermoset propellant and explosive formulations. In addition to them, diisononyl adipate and diisononyl phthalate were used and screened as inert plasticizer candidates for aluminized cast PBX formulations. Mechanical, thermal, and sensitivity properties of PBX formulations were studied and compared in detail. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40907.
