Spherical silver and silver alloy powder produced by ultra-high clean smelting atomization technology are designed and manufactured for the development needs of additive manufacturing, cold spraying and precious metal targets, and have the characteristics of high purity, high fluidity, high sphericity, low oxygen content and controllable particle size. 1. High purity 4N and 5N high-purity silver powder can be supplied in batches, and high-purity smelting atomization powder technology is used to ensure that the purity of the material meets the standards of GBT4135-2016 and GBT39810-2021; 2. High sphericity Through the self-developed production process control technology, the powder products are mainly spherical, and the sphericity is ≥ 0.9; 3. High fluidity The high sphericity of pure silver powder brings excellent fluidity, and the best can reach 12s/50g; 4. Controllable particle size: Pure silver powder with particle size of -20μm, -30μm, 15-53μm, 45-105um, 53-150um and other particle sizes can be prepared according to different application processes to meet the needs of multiple application scenarios; 5. Low oxygen content The unique oxygen content control technology can control the oxygen content according to the application technical requirements, and the minimum can be controlled at ≤150ppm.
