Summary:The invention discloses a production method for sub-micron-level AgSnTe alloy powder. According to the technical scheme adopted by the invention, the key point is that the production method comprisesthe following steps: step 1, weighing Ag, Sn and Te raw materials to mix; step 2 of adding the mixed raw materials in a high-temperature evaporator and internally vacuumizing; step 3 of performing argon gas processing; step 4 of heating and melting the mixed raw materials; step 5 of and evaporating introducing AgSnTe alloy liquid into a particle former; step 6 of continuously adding the mixed rawmaterials, and introducing the AgSnTe alloy powder into a spraying tank; step 7 of collecting AgSnTe alloy powder and liquid-state water through a water circulating powder collecting device; and step8 of performing solid-solution separation to obtain the sub-micron-level AgSnTe alloy powder. According to the production method disclosed by the invention, The raw materials are added to define ohmiccontact between conductive
