Measuring of Nanometer Oxide Powders
Lithium manganese oxides with a fine spherical morphology different from that of the normal composite oxides are formed after detonation wave treatment due to the very high quenching rate.Free metal atoms are first released with the decomposition of explosives,and then theses metal and oxygen atoms are rearranged,coagulated and finally crystallized into lithium manganate during the expansion of detonation process.The growth of lithium manganate via detonation reaction was investigated with respect to the presence of an energetic precursor,such as the metallic nitrate and the degree of confinement of the explosive charge.The detonation products were characterized by scanning electron microscopy.Powder X-ray diffraction and transmission electron microscopy were used to characterize the products.Lithium manganate with spherical morphology and more uniform secondary particles,with smaller primary particles of diameters from 10 to 20 nm and a variety of morphologies were found.
