Abstract
The present invention relates to a metal nanocomposite powder reinforced with carbon nanotubes and to a process of producing a metal nanocomposite powder homogeneously reinforced with carbon nanotubes in a metal matrix powder.
Claims9
A method of producing a metal nanocomposite powder in which carbon nanotubes are dispersed in a matrix, the method comprising:
- (a) dispersing carbon nanotubes in a predetermined dispersing solvent to form a dispersed solution;
- (b) primarily treating the dispersed solution using ultrasonic waves;
- (c) uniformly mixing water-soluble metal salts or metal hydrates with the treated dispersed solution of (b);
- (d) secondarily treating the dispersed solution of (c) using ultrasonic waves;
- (e) drying and calcining the dispersed solution of (d) to produce a metal oxide nanocomposite powder;
- and
- (f) reducing the metal oxide nanocomposite powder of (e).
