摘      要：Nano-powder materials exhibit some novel properties and hence,are aroused general *** preparation technology is more important in preparation nano-powder *** at incident aggregation phenomenon of nanopowder particles,surface modification technology is an effective method in controlling aggregation of nano-powder particles. In the paper,the fundamentals and applied ranges of some surface modification technology are introduced,including thermal decomposition-reduction method,chemical plating,homogeneous precipitation method,sol-gel method,surfaceactive agent method,mcroemulsing method,coupling agent method,esterifying reaction method and surface boundbranch *** surface modification methods in controlling aggregation and ensuring properties of nano-powder particles have some advantages.
