The influence of VO₂(B) nanobelts on thermal decomposition of ammonium perchlorate

The influence of vanadium dioxide VO₂(B) on thermal decomposition of ammonium perchlorate (AP) has not been reported before. In this contribution, the effect of VO₂(B) nanobelts on the thermal decomposition of AP was investigated by the Thermo- Gravimetric Analysis and Differential Thermal Analysis (TG/DTA). VO₂(B) nanobelts were hydrothermally prepared using peroxovanadium (V) complexes, ethanol and water as starting materials. The thermal decomposition temperatures of AP in the presence of I wt.%, 3 wt.% and 6 wt.% of as-obtained VO₂<B) nanobelts were reduced by 39 °C. 62 °C and 74 °C, respectively. The results indicated that VO₂(B) nanobelts had a great influence on the thermal decomposition temperature of AP Furthermore, the influence of the corresponding V₂Os, which was obtained by thermal treatment of VO₂(B) nanobelts, on the thermal decomposition of AP was also investigated. The resufs showed that VO₂(B) nanobelts had a greater influence on the thermal decomposition temperature of AP than that of V₂Os.
