Proposal to buy: utra dispersed copper powder (1,5-2,0 micro Inquiry (采购产品): Proposal to buy: utra dispersed copper powder (1,5-2,0 microns) Dear Sir, We are kindly applying to your esteemed company, Falcon Diversified Manufacturing, Inc., with the proposal regarding a high purity ultra dispersed Copper powder commodity. The commodity we are proposing is a top quality; the purity is 99,998%, which corresponds to natural isotopic abundance. The new technology of the powder production enables to produce very small size particles (up to 1,5 –2,0 and even up to 1 micron). Please find the detailed specification and description about the commodity below. The specification and description of the commodity is as follows: Type: PMU 24-6 CAS No: 7440-50-8 Quality: Purity minimum 99,998%, (please find the analysis chart below) Particle size: 1,5-2,0 microns (there is a possibility to produce up to 1 micron) Method of preparation: physic -chemical The form of particles: spherical Bulk density: 0,69g/cm3 Country of origin: Russian Federation Colour: red-brown Stabilization of powder: inert gas (argon) Intra tare packing: polyethylene ampoules in capacity according to request of a buyer (up to 5 liters), the covers are filled in addition by beeswax Available quantity: >500kg/month Price per gram: USD 3.02 (transportation costs are included into the price) Analysis: Methods of analysis: inductively coupled plasma mass spectrometry and sample combustion in oxygen stream with infrared detection. Equipment: inductively coupled plasma mass spectrometer Spectromass 2000 (Spectral Analyt. Instr. GmbH, Germany) and determination Metavak-CS (MetaVak, Russia). Impurities content are presented as a ppm. 1 ppm=0,0001%. Relative standard deviation of measurements is 10-20% Element Content, ppm Element Content,ppm Al <1,0 Mg 2,0 Ag <10,0 Mn <1,0 As <0,1 Na <10,0 Au <0,1 Ni <1,0 Bi <0,01 Pb <1,0 Ca <10,0 S 36,0 Cd <0,1 Sb <1,0 Co <0,1 Si <10,0 Cr <1,0 Sn <1,0 Fe <10,0 Zn <1,0 Hg 0,3 Cu Matrix Summary: the chemical purity of the copper powder, based on the sum of quoted impurities (Mg, Al, Mn, Re, Ni, Zn, Sb, Pb and Bi) is >99,998%. Relative abundance of Isotopes Isotope Radio For natural copper Measured 63Cu/65Cu 2.245 2.237+0,100 Summary: relative abundance of copper isotopes in tested sample is that of natural. A Certificate of compliance (RoHS) is available. JIS certificate (for Asian market) is available upon request of a buyer. The photos of the particles are available by your request. If you would be interested in our proposal, please contact me at you earliest convenience.
