Nanoscale thermite

Nanoscale thermite, namely A1 (-30-90 nm) and molybdenum trioxide (formulation approx. 40-45% and 60-55% [by wt] respectively) or at O/F mass ratio as 1.4 were studied by Walter and workers for bum rates etc. At the end of the investigation, they concluded that the surface area of M0O3 affects... 

As particle sizes decrease, the sensitivity of the thermite mixture to impact and friction increases. The micron scale thermites are usually quite insensitive to impact and shock, but thermites on the nanoscale can be quite sensitive to both or one of the two depending on the metal oxide. This is exemplified in the work of Spitzer, where a tungsten(VI) oxide and aluminum thermite was prepared by mixing nano and micron aluminum with nano and micron W03. The results of this are presented in Table 13.2. 

On the macroscale, the iron oxide / aluminum thermite is used for the high temperature welding of iron railway rails. This is made possible through its slow rate of energy release and high combustion temperature. On the nanoscale, however, the iron oxide / aluminum thermite behaves very differently. In the literature, this ther-...
