Preparation of Aluminum/Boron/Iron-Oxide Nanothermites and Catalytic Activity for Ammonium Perchlorate

A novel aluminum/boron/iron-oxide nanothermite with a porous structure was synthesized by sol–gel chemistry combined with an ultrasonic method, in which the aluminum and boron were encapsulated in the nanoferric oxide’s skeleton with an average particle size of 50 nm. The catalytic activity of aluminum/boron/iron-oxide nanothermites for ammonium perchlorate decomposition was studied by thermogravimetry/differential scanning calorimetry. Compared with the thermal decomposition of pure ammonium perchlorate, 7 wt % aluminum/boron/iron-oxide nanothermites decreased the decomposition temperature of ammonium perchlorate by 69°C and increased its apparent decomposition heat by 382.3  J/g. The higher catalyst addition favors further decomposition of ammonium perchlorate. Through the investigation of nano-iron oxide, nanoaluminum, and micrometer-boron for thermal decomposition of ammonium perchlorate, the nano-iron-oxide particles play the leading role in aluminum/boron/iron-oxide nanothermites for thermal decompo...
