Abstract:Nanosized anatase, rutile, brookite, and mixtures of these materials taken in different ratios are synthesized using the detonation method with variations in the densities and ratios of explosives composed of the TiO2 precursor, NH4NO3, and C3H6N3(NO2)(3). It is shown that the phase composition, the phase content, and the average particle size of TiO2 nanopowders depend on the composition of the explosive mixtures and their densities. When the weight ratio between the C3H6N3(NO2)(3) compound and the TiO2 precursor lies in the range 0.695-1.270, the average size of rutile particles is larger than that of anatase particles by a factor of approximately two.
