Autoigniting synthesis of gel from Ba(NO3)2, TiO(NO3)2 and C6H8O7·H2O aqueous solution was investigated at an initial temperature of 600℃ and tetragonal BaTiO3 nanopowder with particle size of 80nm was prepared. It is indicated that the specific surface area of the combustion product before and after calcination is 14.74 m2/g and 12.49 m2/g, respectively. The combustion wave is composed of solid phase reaction zone and gaseous phase flame reaction zone. The combustion flame temperature is 1 123 K derived from thermocouple measurement. The characteristics and densification behavior of the sol-gel autoigniting synthesized BaTiO3 nanopowder were investigated.
