The Nanosilver powder we developed have the purity of 99.99% by the physical method.
Our Nanosilver powders are the ones with the highest purity in the world, and very easy to use because the particles are evenly distributed.

Currently, there are several methods in producing Nanosilver, such as Electrolysis, Chemicals, Physical method, etc. A lot of papers and literatures are nowadays mentioning that the physical method is the best environmental-friendly and the most stable method.

Thus, there is no question about the safety of our product.
We will continue to strive further to develop variety of metallic nanopowders.
