Synthesis and Properties of Multimetal Oxide Nanopowders via Nano-Explosive Technique

Abstract:

We demonstrate the methodology of engineering the multi-component ceramic nanopowder with precise morphology by ‘nano-blast’ calcinations decomposition of preliminary engineered nanoreactors. Multiple explosions of just melted C3H6N6O6 embedded into preliminary engineered nanoreactors break apart the agglomerates due to the highly energetic impacts of the blast waves. Also, the solid-solubility of one component into the other is enhanced by the extremely high local temperature generated during each nano-explosion in surrounding area. This methodology was applied for production of agglomerate-free nanoaggregates of Gd20Ce80O1.95 with an average size of 42 nm and LaSrGaMgO3-x nanopowder with an average aggregate size of 83 nm.
