An easy and fast method was design to prepared TiO2/Na2Ti6O13 powders,which by using vacuum detonation method.The mixed explosives were prepared by usage of Ti-Na-contained precursor,ammonium nitrate,hexogen and a certain mass of polystyrene foam ball(EPS)in beaker,and they were detonated in a vacuum detonation reactor to synthesize powders.The prepared frech grey powders were characterized by powder X-ray diffractometer and transmission electron microscopy to ascertain the phase composition and morphology.It found that the powders were consist of TiO2 and Na2Ti6O13,and the TiO2 almost was rutile phase.The intensity of Na2Ti6O13 peak was enlarged with increase of EPS mass.The TiO2/Na2Ti6O13 particles were irregular sphere or long rhombus,and some particles were 10 nm.In generial,the dispersity of the powers was decreased with the mass of EPS increased.
