Abstract
We report the first study of gas generation and thermal wave behavior during the performance of a novel nano-energetic system based on aluminum and bismuth hydroxide Al–Bi(OH)3. Thermodynamic calculations demonstrate that this system is comparable to one of the most powerful known nanothermite systems, Al–Bi2O3, in terms of energy capacity per initial charge mass, and may generate more than twice the gaseous products: 0.0087 mol g1 . Differential scanning calorimetry analysis shows that homogenization of the as-received powder using mechanical activation is an essential step to reduce the decomposition energy of bismuth hydroxide by 30%. This results in nano-thermite with higher pressure discharge abilities. The mechanical activation with energy of 450–750 kJ g1 is enough to transform micro-meter sized particles to sub-micro and nano-sized particles. The resulting nanothermite generated a significant pressure discharge with a value of up to 5.6 kPa m3 g1
