Deflagration products from emulsion explosive unconventional nano-powders from ion reaction

Abstract

Main contents and research results are as follows：First, unconventional emulsion explosives for synthesis of zinc and lithium oxides are designed firstly, and we also discuss mechanics of deflagration. In the final analysis, we succeeded in synthesizing nano-sheets of zinc and lithium oxides by deflagrating at the fist time. Second, we tested microstructures of nanometer thin sheets of lithium and zinc composite oxides.Third, by contrast to industrial emulsion explosives, we analyzed the deflagration mechanics of the unconventional emulsion explosives. Last, zinc and lithium nanooxides are successfully collected and validated by XRD, TEM and FTIR exactly.

Guide for stability evaluation of ammonium nitrate-based emulsions

“…Explosive emulsions (EE) are widely used in blasting operations, such as structural demolition, mineral extraction, quarries and tunneling (Oluwoye et al, 2017;Silva et al, 2006). Recent studies show that EEs can also be used to obtain metallic nanoparticles (spherical zinc oxide, iron oxide, doped copper, nanometer sheets of composites of zinc and lithium oxides) because it is a lowcost method to manufacture nanomaterials on a large scale through controlled detonation (Xie et al, 2006;Wang et al, 2020;Luo et al, 2012;Xie et al, 2009). They are also used in metalworking, explosion, welding, and bar connection because of their acceleration ability (Yunoshev et al, 2018;Yunoshev et al, 2013).…”
