发明名称 METHOD FOR PRODUCING COLLOIDAL ALLOY PARTICLES
摘要 <P>PROBLEM TO BE SOLVED: To reasonably and efficiently produce colloidal alloy particles. <P>SOLUTION: A method for producing colloidal alloy particles is provided in which a binary alloy as raw materials being in a solid state in an ordinary temperature-ordinary pressure environment is heated and evaporated in a pressure-reduced environment, and the generated vapor is cooled, and is condensed and solidified to form alloy particles, and the alloy particles are caught into a liquid medium, wherein (1) the componential ratio of the respective elements in the raw material alloy is adjusted in such a manner that, when the fraction of the number of atomics of the componential elements to the total number of atomics of the raw material alloy is defined as X, the fraction of the vapor pressure of the componential elements to the total pressure of the vapor of the raw material alloy falls within the range from X-0.1 to X+0.1, and (2) the raw material binary alloy is made of alloy species forming a uniform alloy phase in an alloy lump. <P>COPYRIGHT: (C)2008,JPO&INPIT
