   - Copper purity: 5N (≥99.999%), 6N (≥99.9999%), or higher
   - Particle morphology: Spherical, non-layered structure
   - Particle size: Nano to micron range
   - Target particle size: 1–7 μm, or other available sizes
   - Particle Size Distribution: D10 / D50 / D9
   - Detailed impurity analysis, including O, C, Fe, Ni, Zn, Pb, S and other metallic impurities
   - Manufacturing process and raw material source
   - Production capacity by purity grade and particle size

2. Quality Documentation Please provide, if available:
