Nanopowder using a plasma combustion device and a manufacturing method thereof are provided to supply proper heat energy to a precursor by locating a powder injecting nozzle 0.1-3cm away from a central part of an induction coil. A method for manufacturing nanopowder comprises the following steps of: preparing magnesium oxide powder(MgO) with 10mum-100mum of diameter and rare-earth-metal oxide powder(201); mixing the prepared magnesium oxide powder and rare-earth-metal oxide powder mechanically(203); injecting the mixed powder together with a carrier gas into an RF plasma combustion device; supplying a central gas and shielding gas to the RF plasma combustion device(213); and supplying a quenching gas to the RF plasma combustion device(215). |
