CERAMIC POWDER CONTAINING METAL NANOPARTICLE, ITS MANUFACTURING METHOD AND METHOD FOR MANUFACTURING CERAMIC-METAL-BASED NANOCOMPOSITE

摘要

PROBLEM TO BE SOLVED: To easily realize a ceramic-metal-based nanocomposite having an ideal intraparticle nanocomposite structure and to obtain the ceramic-metal-based nanocomposite which can demonstrate excellent characteristics.

SOLUTION: As a preparation process, gamma alumina powder 10 having a pore 2 and an aqueous solution 3a containing metal ions are prepared. As a dipping process, the γ-alumina powder 10 is dipped into the aqueous solution 3a in order to produce slurry 11. And as an impregnation process, the aqueous solution 3a is infiltrated into the pore 2 of the γ-alumina powder 10 by carrying out vacuum suction of the slurry 11 so that a ceramic powder containing metal nanoparticles is obtained. The ceramic-metal-based nanocomposite having excellent characteristics is obtained by sintering the ceramic powder containing the metal nanoparticles.
