Abstract: PURPOSE: A preparation method of a stable mono dispersion phase element having a particle diameter of about 1-20 nm, an alloy, an intermetallic compound, and over-coated magnetic nanoparticles is provided which results in a low cost and convenient chemical process CONSTITUTION: The process comprises a)a process for forming a metallic precursor solution from a transition metallic salt, an ionic surfactant and an inactive solvent containing at least one alkylphosphine and an organic stabilizing agent such as oleic acid at room temperature or at 22000-300°C, b)a process for pouring the metallic precursor solution in the surfactant, c)a process for adding a flocculant to the solution for settling nanoparticles containing acid and acetylamide ligand there around without a permanent coagulation, d)a process for adding hydrocarbon solvent containing one of phenyl ether and n-octyl ether for redispersing or repeptizing
