Copper Isotope Powder

Description

Our product of electrolytic, ultra‐dispersed copper powder. Electrolytic copper powder is typically used for sintering in powder metallurgy and electronic materials. Classical applications include oil‐retaining bearing alloys, mechanical parts, current‐collecting materials, friction materials, electrical contacts, and others. Specifications for high quality copper powder used for such applications ensure the product is *9.**5% pure in natural copper with metallic impurities and having a particle size of less than 5um. Our product has been analyzed by GIREDMET Testing Analytical Center (, Lot #*****3‐*4), and Institute Fresenius , Lot #****6). Chemical analysis was performed using Spark Source Inductively Coupled Mass Spectrometry as well as Inductively Coupled Plasma Mass Spectrometry for multi‐elemental cationic contaminants and isotopic speciation of copper. Particle size was determined using a microsedimentometer. Analyses were performed in accordance with valid analytical techniques. Certificates of analysis from both laboratories conclude our product to be *9.**9% chemically pure based on metallic impurities of Al, Cr, Mn, Ni, Zn, Ge, Mo, Cd, Sn, Sm, and Re. The isotopic ratio is that of natural copper (*9.1% *3Cu : *0.9% *5Cu). Particle size was determined to be an average of 2.*4um with a spherical configuration. The quality of our electrolytic, ultra‐dispersed copper powder meets or exceeds industry standards. The powder is properly stowed in sealed containers with a moisture barrier and secondly reinforced in polyethylene bags. Product is currently stored in a secure and bonded warehouse in the US and ready to ship
