Abstract: The α-Al2O3 nanoparticles were prepared by the combustion synthesis method, The lattice parameters of α-Al2O3 were determined by XRD at temperatures ranging from roomtemperature to 1100℃, the thermal expansion coefficients of △α/α0; △c/c0 and △V/V0 per℃ of α-Al2O3 lattice were 7.27×10-6/℃, 7.50×10-6/℃ and 21.92×10-6/℃ respectively.

Key words: a-Al2O3, nanopartides, combustion synthesis, lattice thermal expansion coefficients, dynamic high temperature powder XRD
