Capacitor Grade Ta Tantalum Nanoparticles

Tantalum Nano Powder with the characteristic of slushing which use for the electronics and chemical industries.

Superfine nickel nanopowders could do 20nm nano size, 99.8% purity, high acitve, generally do passivated surface treatment.

Silicon oxide nano powders (SiO2,20NM,99.8%,Amorphous) Silicon oxide nano powders as the amorphous white powder, is a kind of non-toxic, tasteless, no pollution non-metallic materials. silicon oxide nano powders modification: 1. Alcohol, acid modification Experiments showed that alcohol and acid compounds will react with a large number of -OH of silicon oxide nano powders surface, so organic groups are grafted in the surface of nanoparticles, and the hydrophobic properties of the modified powders got improved, so as to improve the compatibility of the nano powders and organic matter 2. Surfactant modification 1) by physical adsorption surfactant is adsorbed on the surface of nanoparticles; 2) certain groups of surfactant react with -OH of the surface of the particles,which achieve the goal of the surface modification of the particles. 3. The silane coupling agent modification Experiments show that the coupling agent reduce the interaction between particles, and influence degree of different coupling agent on the modified samples is different. Stock# M600 and M602: hydrophilic SIO2, 10-20NM and 20-30NM,99.8% Stock# M603 and M606: hydrophobic SIO2,10-20NM and 20-30NM,99.8%                        1kg per bag for sample, 10kg per bag for the hydrophilic, 5kg per bag for the hydrophobic The main application of silicon oxide nano powders       HONGWU NANO silicon oxide nano powders, more than 8 years of market and technology development, has been widely used in electronic packaging materials, polymer composite materials, plastics, coating, rubber modified, paint, ceramics, adhesive, glass fiber reinforced plastic, drug carrier, cosmetics and sterilization field, which bring epoch-making significance for an upgraded version of a traditional product.
