Spherical high-purity silver powder properties
|
|
Silver (Ag) is one of the earliest metals developed and utilized by humans. Sterling silver is a silvery-white metal with strong metallic luster, a melting point of 961.8 °C, a density of 10.5g/cm³, stable chemical properties, not easy to oxidize at room temperature and good ductility and plasticity. Silver is classified as a precious metal with high reflectivity, thermal and electrical conductivity, and antimicrobial properties, so silver and related alloys are increasingly used in new energy, electrical and electronic industry, biomedical, jewelry semiconductors, and other fields.
Sterling silver powder material properties:
Sterling silver powder material properties:
1. High purity
It can supply 4N and 5N high-purity silver powder in batches, and use high-purity smelting atomization powder technology 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 finally spherical, and the sphericity is ≥0.9;
3. High liquidity
The high sphericity of sterling silver powder brings excellent fluidity, up to 12s/50g;
4. The particle size is controllable
Sterling silver powder with particle sizes 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.
