High purity molybdenum wire and its production method, relates to the molybdenum products production process of metal materials, especially the production method of high purity molybdenum wire. The invention adopts TMA-52 chelating agent dissolved in deionized water, the TMA-52 chelating agent solution formed as MoO2 raw material detergent, and then the MoO2 after washing is dried, and then the molybdenum powder is successively reduced, the molybdenum billet is pressed, the molybdenum billet is sintered, the molybdenum bar is forged, and finally the molybdenum wire with content ≥99.984% is generated by drawing.
