We pay special attention to the quality assurance of the products and services we deliver. We believe that this is the best way to make products work as effectively as possible. 400nm batio3, 30-50nm Copper Oxide Nanoparticles , Silicon Si Metal Powder , 70nm Tantalum Nanoparticles ,Copper Oxide Nanopowder . Our main focus is on the nano sized powder and particles. We stock a wide range of particle sizes for 10nm to 10um, and can also fabricate additional sizes on demand. Our products are divided six series hundreds of varieties: the elemental, the alloy, the compound and the oxide, carbon series, and nanowires. The product will supply to all over the world, such as Europe, America, Australia,Bulgaria, Kenya,venezuela, Cape Town.Carbon Nanotubes (SWCNT,DWCNT,MWCNT and functioned nanotubes) ;
