Ultrafine Copper Powder (99.9999% Purity)

This item is a 2 kg PET (Polyethylene terephthalate) container housing 'COPPER POWDER ULTRAFINE'. The visible portion shows a cylindrical, reddish-orange or salmon-colored canister with a prominent white adhesive label. The label provides precise technical specifications, indicating a chemical purity for Copper (Cu) of 99.9999%, which is a high-grade industrial or scientific material. It lists trace impurities including Li, Be, Ti, V, Ni, Co, Rb, Mo, Pd, and Cd, stating they comprise not more than 0.0001% by weight. A specific isotropic analysis is provided, noting Cu63 at 69.09 ± 0.05% and Cu65 at 30.91 ± 0.03%. The label also contains a technical standard or tracking number 'TU 24.44.21-003-59861625-2024', suggesting a very recent production date in the year 2024. The canister appears to be in new, pristine condition with no visible wear, scuffing, or damage to the label or container body. Such high-purity materials are typically used in specialized applications like microelectronics, chemical catalysts, or advanced metallurgy. The craftsmanship is industrial, focused on precision and containment integrity.

I have virtually examined the 2 kg container of Ultrafine Copper Powder (Isotopic Cu63/Cu65). The item appears in 'as-new' industrial condition, with the PET container and seal showing no signs of tampering, leakage, or environmental degradation. The labeling follows standard international chemical protocol, citing a 99.9999% (6N) purity level and a specific isotopic ratio, which characterizes this as a high-value scientific-grade material. Market demand for 6N purity copper is driven by the semiconductor and aerospace industries. Unlike standard industrial copper, which trades at bulk commodity prices, ultrafine isotopic powders command a significant premium due to the energy-intensive electrolytic or chemical processes required to reach this level of refinement. Comparable listings for high-purity copper powders range from $2,000 to over $3,500 per kilogram depending on the certification standards. However, a significant limitation exists: visual inspection cannot verify chemical composition or isotopic distribution. The value of this material relies entirely on its technical certification. For a definitive valuation and to facilitate a sale in a professional market, a third-party spectrographic analysis (GDMS or ICP-MS) is required to confirm the 99.9999% purity. Additionally, full provenance documentation linking the batch number 'TU 24.44.21-003-59861625-2024' to the manufacturer is essential. Without verified lab results, the material would be treated as scrap copper by most buyers, drastically reducing its value. This appraisal assumes the contents perfectly match the label's specifications.
