Ti/CuO and Ti/CuO/Cellulose Nitrate Nanothermites: An Early Insight into Their Combustion Mechanism

open access: yesEnergies
Most nanothermite compositions utilise Al as a fuel, due to its low cost, high reactivity and availability. Nevertheless, aluminothermites exhibit high ignition temperature and low active metal content.

Effect of additives on CuO/Al nanothermite properties

open access: yesJournal of Physics: Conference Series, 2017
The effect of additives on CuO/Al nanothermite properties is reported. The incorporation of additives resulted in the decreased sensitivity. It had an adverse impact on gas dynamic characteristics of CuO/Al nanothermite, up to the loss of the unique capability of burning in narrow channels.
