Ammonium nitrate (AN) is widely used as an oxidizer in propellants, explosives and pyrotechnics. Some of the disadvantages of ammonium nitrate can be reduced by using Mg-Al alloy as a fuel. The effects of zirconium oxide (ZrO2) on the burning characteristics and thermal properties of AN/Mg-Al – based pyrotechnic mixtures have been studied. The addition of ZrO2 increase the burning rate significantly and lowers the pressure deflagration limit (PDL) from 2 MPa to less than 1 MPa. Differential Scanning Calorimetry investigated the thermal decomposition characteristics at different heating rates, and the activation energies were evaluated. With the addition of Mg-Al alloy to pure AN, the main peak shifts lower at approximately 100 oC. At the same time, ZrO2 does have a significant influence on the thermal properties of both of AN and AN/MgAl. The addition of MgAl alloy and ZrO2 reduces the activation energy.
