STUDY OF NANOPOWDER PRODUCTION BY GAS-EMBEDED ELECTRICAL EXPLOSION OF WIRE

摘要：

Electrical explosion of wire (EEW) in embedded-gas is a simple and efficient method for producing nanosize powder of metal, alloy, or metal compound. In this paper,a simple EEW device is constructed. It consists of a low inductance 2 μF capacitors typically charged to 10-30 kV,a triggered gas switch, and a production chamber housing the exploding wires. With the EEW device nanosize powders of copper oxides and titanium oxides were successfully synthesized, and the effect of gas pressure on the average particle size is experimentally investigated. The synthesized powders were analyzed by X-ray diffraction, transmission electron microscopy, and BET surface area analyzer. As a result, the size of the most powders synthesized with right experimental conditions is found to be smaller than 100 nm, and the average particle size is about 50nm.
