Abstract:
1. A method for fabricating ceramic nanocomposite powder, said method comprising: (a) dispersing carbon nanotubes in a dispersion medium, wherein the dispersion medium is selected from the group consisting of water, ethanol, nitric acid solution, toluene, N,N-dimethylformamide, dichlorocarbene, and thionyl chloride; (b) sonicating the dispersion resulting from (a); (c) dispersing a water-soluble salt in the sonicated dispersion resulting from (b), wherein said water-soluble salt, mixed with the carbon nanotubes, consists of metal-based salts capable of being formed into a ceramic matrix post calcination; (d) sonicating the dispersion resulting from (c) for 2 to 10 hours, the dispersion consisting of the carbon nanotubes, the water-soluble salt, and the dispersion medium; and (e) drying and calcinating the sonicated dispersion resulting from (d); thereby fabricating ceramic nanocomposite powder, wherein said carbon nanotubes are homogeneously dispersed in said ceramic matrix, and wherein chemical bonds are formed between the carbon nanotubes and the ceramic matrix.
