| Abstract: | The thermal properties of Alex, a nanosized Al powder, were determined using various techniques, including DSC, TG, simultaneous
TG-DTA (SDT) and accelerating rate calorimetry (ARC). The results demonstrate that the specific heat capacities of nano and
micron size Al powders are similar between 30 and 400°C. Dynamic and isothermal methods were used to determine the kinetic
parameters for the oxidation reaction of Alex, which was detected at an onset temperature of 481°C. The results obtained were
in good agreement with each other. From the ARC experiments, exotherms were detected near 340 and 260°C for experiments started
at ambient pressure and at 0.72 MPa, respectively.
