Abstract
We demonstrate a unique processing technique which we term the nano-explosion synthesis of multi-metal oxide nanopowders. This technique is based on engineering multi-component ceramic nanopowder with precise morphology by nano-blast deagglomeration/calcination. Multiple nano-explosions of impregnated cyclotrimethylene trinitramine deagglomerate the nanopowder due to the highly energetic impacts of the blast waves, while the solid-solubility of one component into the other is enhanced by the extremely high local temperature generated during the nano-explosions. We successfully applied this technique to produce nanosize agglomerate-free ceria-gadolinia solid solution powder with excellent morphology and an average aggregate size of 42 nm. In addition we synthesized lanthanum strontium gallium magnezium oxide nanopowder.
