Ag Nano Powders
Description
Ag is a ductile and malleable metal that is chemically stable and has many
excellent properties, including thermal and electrical conductivity. Ag
reflects light well. When converted into nano-sized materials, Ag has better
activity and higher specific surface area, which significantly improve its
functions and even give rise to new functions for new applications. For
example, Ag nanoparticles have an excellent antimicrobial ability, so they
can be extensively used in daily life as a natural antimicrobial agent. Additionally, with exceptional electrical conductivity, Ag nanoparticles can beused to make conductive paste or ink for applications in optoelectronic
semiconductor devices or to replace existing materials for better
functionality.

Applications :Electronics: Conductive patterns of PCB
Coatings: Infrared ray-blocking stealth coatings
Physical chemistry: Catalysts
Biomedicine: used for antimicrobial purposes
Energy: Conductive materials for photovoltaic cells

Cu Nano Powders
Description
Cu is a soft reddish-brown metal with great ductility and malleability. An
abundant element on the Earth, copper has a face-centered cubic (FCC)
structure, and it can react with oxygen to gradually form Cu oxides on thesurface. Cu is often used in the production of alloys and as a major
construction material for its excellent mechanical properties. At room
temperature, the electrical (59.6×106 S/m) and thermal conductivity (401W/mK) of Cu is second only to that of Ag. Due to its relatively low cost,copper is a common material in electronic components, cables, andelectrical apparatuses. Cu nano powder can even be used in the end
materials of cutting-edge microelectronic materials, lubricants, machinery,catalysts, etc.

Applications :Electro-ceramics: End materials of multilayer ceramics
Physical chemistry: Catalysts for the preparation of alcohols
Coatings: Conductive coatings & pastes; paints; construction materials
Machinery: Hard alloys; tools & crafts; lubricants
Pigments: Additives of chemical dyes

Ni Nano Powders
Description
Ni is a transition element. As a bulk material, Ni is a silver-white
metal with sheen whose density is 8.9 g/cm2, melting point is 1450℃, and crystal structure is mostly face centered cubic (FCC)
lattices. Ni is ferromagnetic at room temperature and antiferromagnetic at 355℃ or over. When converted into nano-sized materials,
Ni has a greater activity, which leads to novel functions. Thesefunctions are dependent on particle sizes and show significantly
different performances at different size ranges, allowing flexibility inapplications. In addition to ferromagnetism, nano-sized Ni also
draws attention to its electrical conductivity and applications incatalysis.

Applications :Energy: Electrodes of fuel cells
Physical chemistry: Catalysts
Electronics and semiconductors: Conductive materials
Biomedicine: Magnetic materials
