METAL NANO-PARTICELS HAVING CONTROLLED SINTERING CHARACTERISTIC USING PHASE SEPARATION AND SINTERING METHOD USING THE METAL NANO-PARTICLES

摘要

The present invention relates to particles used in controlling sintering characteristics in a sintering process of powder, and to a powder sintering method using the same. More specifically, the purpose of the present invention provides metal nanoparticles which can soundly be sintered together with a different type of material as a sintering activating effect caused by a particle refining effect can be controlled. The metal nanoparticles having a sintering capacity controlled by a phase separation phenomenon comprises: a first metal; and a second metal, wherein the second metal is in the first metal in a supersaturated solid solution state, and the sintering of the first metal is inhibited or facilitated by the phase separation of the second metal into nanoparticles in the sintering process of the first metal.
