ABSTRACT:
The method for synthesizing metal oxide nanopowder produces powders of nanoparticle size from metals having relatively low boiling temperatures, such as zinc, tellurium, bismuth, and strontium by vapor-phase oxidation using a conventional 2.45 GHz microwave oven. The energy that initiates the combustion comes from the microwave through a susceptor tube that absorbs radiant microwave energy and transfers it to the metal, which evaporates to small particles inside the susceptor tube and then combusts in air to form nanosize powder. The susceptor is made of silicon carbide composite material.
