Preparation method of aluminum oxide-carbon nano tube composite powder material
The invention discloses a preparation method of an aluminum oxide-carbon nano tube composite powder material. The preparation method comprises the steps of through a chemical vapor deposition method, taking a metal organic precursor as a raw material, under the temperature condition of 400 to 800 DEG C, taking metal nano particles formed on the surface of aluminum oxide powder as a catalyst, simultaneously pumping carbon-rich gases such as methane and acetylene, and enabling carbon nano tubes to grow in situ, so as to obtain an aluminum oxide-metal nano particle-carbon nano tube composite powder material. Through changing various parameters such as the weight of the organic raw material, the flow or constituent of a reactant gas and reaction temperature, the decomposition of the raw material and the generation of the metal nano particles and the carbon nano tubes are adjusted, and the size and the microstructure of the powder is controlled. The method has the characteristics of being simple, short in preparation period and the like, and the prepared aluminum oxide-metal nano particle-carbon nano tubes are uniformly distributed, and have wide application prospect in multiple fields such as conductive ceramics and catalytic materials.
