Nano-powder and a manufacturing method thereof using plasma combustion are provided to manufacture less than 100nm of nano-powder by optimizing the kind and speed of powder injecting gas, quenching gas and shielding gas. A method for manufacturing nano-powder comprises the following steps of: preparing magnesium oxide(MgO) powder and metal oxide powder with 10-100mum of diameter(201); mixing the prepared powder mechanically to obtain mixed powder(203); injecting the mixed powder together with powder injecting gas into an RF(Radio Frequency) plasma combustion device; supplying center gas and shielding gas in the RF plasma combustion device(213); and supplying quenching gas in the RF plasma combustion device(215). |
