Abstract:

This paper introduces the common preparation methods of nickel nano-powder such as the plasma, liquid phase reduction, spark discharge erosion and high energy ball milling. The advantages and disadvantages of these methods are summarized. There are however still several problems in the preparation of nickel nano-powder. For instance, it is difficult to achieve large-scale production and the purity and performance are difficult to meet the application requirements. The research trends are concluded as analyzing the nucleation and growth mechanism, and finding the best synthesis conditions to prepare the nickel nano-powder controllably. In addition, this paper describes the application status and demands of nickel nano-powder in MLCC and catalysts and points out that the problems of easy oxidation, poor matching with other materials need to be overcome. It is necessary to optimize its performance by surface modification or by other ways. At last, the research tendency of nickel nano-powder in the future are to bind the application of nickel nano-powder with its preparation method, that is using the most suitable preparation method to meets the application requirement.

Key words: nanomaterials, preparation, plasma method, liquid phase reduction method, multilayer ceramic capacitor, catalyst
