Nanopowder production system
Nanopowder production system
Electrical explosion of wire (EEW) is a method for producing of nanopowders in pilot and mass production scale. The method is based on pulse discharging of stored electrical
energy bank (capacitors) into metallic wire. Discharging of high amount of energy in a very short time (micro seconds) into metallic wire results in controlled explosion of wire.
Typically, this system consists of pulse power, explosion chamber and collecting system. Continuous feeding of wire into reaction chamber provides possibility for production
of considerable amount of nanopowders.
Advantages
• Simple and accurate process control
• Continuous production process
• High production rate
• The possibility of producing a variety of nanomaterials with a single system
• Safe and secure system
• Compact design
Application
This method can be used to produce a variety of metallic, oxides and nitrides nanopowders. In general, the metals that can be rolled into wire form can be used as input to
the system and chemical composition of nanopowders can be controlled by chamber’s atmosphere. Nanopowders produced in this way other than research application can
also be applied in several industries such as coating, colors, cosmetic and hygiene.
