The metal nano- particle which is produced production method of the colloidal solution of the metal nano- particle with and that

摘要

As for production method of the metal nano- particle colloidal solution due to this invention, while agitating the aforementioned electrolytic aqueous solution, after opposing arranging the metal electrode of pair, due to churning expedient in the electrolytic aqueous solution which the metal salt is melting by the fact that it impresses electric current in the electrode of the aforementioned two, the metal ion in the solution being restored, in order for the metal nano- particle to precipitate, adding the poly- solvate in the aforementioned electrolytic aqueous solution in the production method of the colloidal solution of the metal nano- particle which is manufactured, by coating doing the outside of the metal nano- particle which it precipitates from the electrolytic aqueous solution, the metal nano- particleIt features that cohesion is prevented.
