The present invention provides a method for producing a thermal plasma jet, comprising the steps of: (1) generating a thermal plasma jet by supplying a thermal plasma jet generating gas; Melting and vaporizing the gallium source powder using the thermal plasma jet generated in step 1 (step 2); Injecting a reactive gas into the vaporized gallium raw material powder in step 2 (step 3); And cooling the vaporized powder (step 4). The present invention also provides a method for producing a gallium nitride nano powder. The method for producing gallium nitride nano powder according to the present invention has the effect of mass-producing gallium nitride nano powder having high purity and high crystallinity in a short time by producing gallium nitride nano powder using thermal plasma jet . In addition, gallium nitride can be prepared using gallium powder as well as gallium compound powder, particularly gallium nitrate hydrate, which is an economical raw material, as a gallium raw material powder for producing gallium nitride nano powder.
