Copper Nano Powder

We currently produce two (2) types of nano-powders in production:
The first and most expensive is the nanopowder isotopic obtained a new hydrometallurgical process (physical-chemical free hydrazine).
The second product is a nano-powder of metallic copper, which is obtain through a physical process, with excellent results in ultrafine particles such as flakes.

Copper nanopowder Isotopic Impurities
GENERAL:The isotopic copper nano-powder (ultra and impalpable powder) is used for manufacturing Cu63 and Cu65 isotope for nuclear medicine applications, production of radioisotopes and applications in the pharmaceutical industry, electronics, military applications and nuclear physics. Currently it is expanding its market with new technologies in nanotechnology.
There are three (3) main methodologies for the production of copper powder and stable isotopes natural:
Distillation, Centrifugation Enrichment and Enrichment Electromagnetic.
The distillation only works effectively when there is a big difference relative mass of different isotopes of an element. The electromagnetic system is capable of enriching the isotopes of most elements, but it is expensive to operate and only in relatively small quantities. Other methods used are enrichment laser, chemical enrichment and separation of plasma.
In this case, it is produced through a powder metallurgy technology specially developed to obtain a pure copper powder particles 99.98% at .0.5, achieving excellent dispersion and nano-powder surface coverage as The smaller particles (spherical), the greater their properties and their value on the market.
Our product, which has taken about 5 years of development, has a particle size outstanding and has been certified in relation to the purity and of IGAS Research in Germany, the most important laboratory in the market for nanopowders.
Obtaining free copper powder Hydrazine (Isotopic nanopowder).
As noted, the copper nanopowder can be obtained from physical methods (Grinding and further atomization plasma arc), by electrophoresis and / or scanning mail.
These methods produce agglomerated particles of different sizes and different course.
Copper states (+1 and +2), the spontaneous oxidation process. However, related to the metal properties are often affected in a negative way especially when final destination is produced of ceramics and / or alloys.
A more effective method to obtain non-agglomerating spherical particles is by aqueous chemical reaction of copper sulfate by the addition of hydrazine and subsequent separation by using ammonium COPPER. This method generates particles sphere of a size greater than 0.5 microns with a tendency to spontaneous oxidation pigments form of the species reacting with valence +2, forming cupric oxide (CuO), whose activity is related to the area of pigment by its color black, high toxicity.
The other species is formed cuprous oxide Cu2O, this species is responsible for the biocidal properties. This method generates a number of impurities according to the requirement ranging from 27 to 64.
1. By selective replacement of the lattice from copper sulfate penta hydrate(CuSO4X 5H2O) in the absence of hydrazine or ammonium complex COPPER. This is a new obtaining model.
2. Free spherical particles aggregation, impalpable, ranging in size from 0.2 to 0.5 microns as required. Larger sizes can also be obtained. This was determined under Scanning Electron Microscopy, whose report is available.
3. By the method of obtaining patent pending, the copper powder obtained no alterations in their physicochemical properties such as electro driving.
