Application of Silicon Dioxide as the Inert Component or Oxide Component Enhancer in ANFO

Non-ideal explosives with differing contents of silicon dioxide (silica or dioxosilane) added in the form powder and gel were tested. Measurements structure, crystallinity morphology performed by means infrared spectroscopy (IR), X-ray diffraction (XRD) scanning electron microscopy (SEM). IR XRD analysis revealed a lack SiO2 influence on non-ideal explosive structure. SEM indicated that all surface deformations ammonium nitrate(V) prill filled thin fuel film layer which was present. The additional calculations selected theoretical properties compositions made using ZMWCyw software. Based this, it established optimum semimetal content 1.0 wt.%. Blasting tests confirmed addition wt.% to Ammonium Nitrate Fuel Oil (ANFO) resulted lowest volume post-blast fumes. Moreover, finer cannot be used as oxide component enhancer due inhibition detonation reaction. should only an inert component.
