Abstract

NiAl/Al₂O₃ composite were synthesized by thermite reaction of nickel oxide and aluminum powder mixtures. The phase, the microstructure of the composite, as well as the thermite reaction mechanism, were investigated by X-ray diffractometry (XRD), scanning electron microscopy (SEM) combined with differential scanning calorimetry (DSC). The experimental results show that the thermite reaction leads to the interpenetrating network structure of NiAl/Al₂O₃ at 1223K for 60 min and the chemical reaction apparent activation energy is E_ap=166.960±13.496 kJ·mol⁻¹ in the NiO/Al system.

Keywords
