Abstract: Disclosed is a method for manufacturing a low melting point nano glass powder. The method includes the steps of: preparing a bismuth-based low melting point glass powder precursor of a micro size, having bismuth (Bi) as the main ingredient; injecting the glass powder precursor into a reaction chamber of a plasma treatment device; applying thermal plasma via a direct current power source to the glass powder precursor injected into the reaction chamber, to vaporize the glass powder precursor; and generating nano glass powder having a nano size by quenching the gas generated by vaporizing the glass powder precursor.
