“…In the case of cartridged EEs, the above limitations can be avoided and it is therefore much easier to modify the detonation parameters of such blasting agents. Many studies report the use of demilitarised high explosives, such as TNT [ 11 ], RDX [ 12 ], Composition B, HMX and NC/NG-based smokeless powders [ 13 ], as supplements to EEs, allowing disposal of those explosives and increasing the energetic parameters of such supplemented EEs formulations [ 14 ], but those high explosives need not originate from reclamation efforts, as pristine high explosives are reported to be used as EE sensitizing supplements [ 15 ]. It should be noted, however, that emulsion explosives should, by design, consist of safe and non-explosive components, supplementing them with high explosives does not comply with this design and compromises the increased production, handling and usage safety of emulsion explosives.…”

Bulk emulsion explosives, although they are very convenient and safe to use, also have disadvantages, with the main one being the relatively low power in relation to cartridged emulsion explosives or classic nitroesters (e.g., dynamites). Therefore, materials of this type currently have only limited use. In addition, these materials are characterized by the variability of blasting parameters over time from loading into the blasthole, which is closely dependent on the utilised mining method of the mine, which makes it difficult to precisely control the fragmentation. The industry is trying to respond to the demand for bulk emulsion explosives with increased energy and improved parameter stability, but so far it has not been possible to do so in a safe and effective way. Methods of improving blasting parameters mainly rely on additives to oxidant solutions during production, which creates additional risks at the production stage, as it involves handling hot and concentrated ammonium nitrate solutions, for which there are known cases of uncontrolled decomposition of such solutions, even leading to an explosion. This paper presents a method of improving the thermodynamic parameters and the stability of the sensitization reaction without the need for changes in the oxidant solution.

“…Obviously, the ideal way of solving the problem of quality and costs is reducing the critical thickness of explosives. For this purpose, Several explosive mixtures such as RDX powders and baking soda, PETN and baking soda, and HMX and emulsion explosives have been investigated by researchers [18][19][20]. It was found that these explosive mixtures were suitable for the explosive welding of foils, due to their low critical thickness and low detonation velocity.…”

To make industrial explosives suitable for explosive welding of metal foils, colloid water was used as a covering of explosives. The effect of the colloidal water thickness on the critical thickness of the explosives was investigated, and then AA1060 foil and Q235 steel plate were bonded using this method. Additionally, the bonding properties of the clad plate were studied through mechanical performance tests and microstructure observations. The results show that the colloid water can significantly reduce the consumption of explosives and avoid excess energy in foil weld, due to the low critical thickness of explosives in this condition. The AA1060/Q235 composite sheet shows an excellent bonding quality without macroscopic defects except for the boundary area, and no separation, tearing or fracture was observed under bending load. The microstructure results show a wave‐type metallurgical bonding between the two materials, with some melting zones in the crest. In addition, a hardening phenomenon near the AA1060/Q235 interface was revealed by microhardness and fractography studies on the tensile specimen.
