“…To avoid such problems and to have the liberty of using higher voltages, the resistivity of fuel and oxidant has been examined separately in the present work. A voltage range of 0.6 V to 1000 V and packing densities , which approaches the 4-30 kV·cm −1 values generally observed in ESD generated sparks [24]. Ω·cm were recorded, which are high when compared with the 10 1 -10 3 Ω·cm reported in deposited films [25].…”

Abstract:The sensitivity of nanothermites to electrostatic discharge (ESD) has been noted by many authors. In the present work, nanothermites have been prepared using aluminium fuels with oxide 11 Ω·cm exceeds that of the oxidants studied. An ESD sensitivity trend, based on a reduced proportion of spark current carried by the aluminium fuel, is proposed and was consistent with the observed ESD and resistivity data.

“…12 Ω·m and 1.1×10 11 Ω·m respectively, which indicates that they will have a potential for discharging due to the generally held view that, for bulk materials, 10 10 Ω·m is the lower limit at which cone discharges are likely to occur [1].…”

Abstract:The electrostatic hazards of nitramine explosives (RDX, HMX) were assessed in this paper. The resistivities of different particle-size RDX and HMX were tested by a device designed and manufactured according to the standard ISO/ IEC 80079-20-2:2016. This work shows that the resistivities of uncompacted RDX and HMX increase as the particle size decreases. Charging characteristics test experiments were also carried out using a so-called sieve method. Using this method, the influence of aperture size on charge accumulation of RDX was studied, and the characteristics of electrostatic accumulation of different particle-size RDX and HMX sieved with 50 mesh standard sieve were compared. The results show that the absolute value of the charge accumulation increases as the mesh number increases (i.e. the aperture size decreases), and increases as the particle size is decreased, indicating that nano-sized RDX and nano-sized HMX accumulate static electricity more easily than conventional micron-sized ones. Finally, the electrostatic discharge (ESD) sensitivity of nano-sized RDX and nano-sized HMX was investigated. Nano-sized nitramine explosives were found to have a higher ESD sensitivity than micron-sized ones.
