Dear Sir,
As of our experiences in observing the trade copper powder
63/65, material of a chemical purity in the range of
99,995-99,999% Cu, currently is value at
about 4$ -per
milligram.
The isotopic composition of this sample is that of natural
copper. The material is not radioactive!
The chemical purity, based on the determinated imputies Al,
Cd, Fe, Mg, Mo, Ni, Sb, Ti, Zn,
is:
(TU
1793-o11-50316079-2004)
99,997%
The material which refers to the IGAS certificate No.021760, dated
25.03.2008, is of that quality and thus of that value.
* Specifications: purity-99,997%, Cu 63/65-natural. We have
certificate GIREDMET and all documents. Price- $ 4 per gramm.
Ultrafine Copper Powder Dispersal PMU Type
99,997 Ultrafine copper powder superfine dispersal PMU
type, net weight 1000 KG with the purity grade of 99.997%. Cu63 and
Cu65 are the only stabile isotopes in copper. It is not radioactive
and not toxic.
All supporting documentation and certificates can be sent
additionally. Origin: Russia Certificate: IGAS Quantity: up to 1000
kg Price: 4$ per
gram (negotiable)
