Title:
METHOD FOR PRODUCING AGGLOMERATION OF NANOPARTICLES OF METAL OR METAL OXIDE BY ENCLOSING NANOPARTICLES OF INDIVIDUAL METAL OR METAL OXIDE WITH SOLID ORGANIC COMPOUND AND VAPORIZING ORGANIC COMPOUND
Document Type and Number:
Japanese Patent JP2023026255
Kind Code:
A
Abstract:
To provide a method for producing an agglomeration of nanoparticles of not only a metal, but also a metal oxide free of impurities using an inexpensive raw material through an extremely simple treatment.SOLUTION: In a method for producing an agglomeration of nanoparticles of a metal oxide, a metal or a metal oxide is subjected to thermal decomposition and crystallization and the crystal is crushed to prepare an agglomeration of nano-sized fine crystals, which are enclosed with a solid organic compound. The fine crystals are then subjected to thermal decomposition to prepare an agglomeration of nanoparticles of a metal or a metal oxide covered with the solid organic compound. Further, the solid organic compound is subjected to thermal melting and then vaporized to prepare an agglomeration of nanoparticles of a metal or a metal oxide.SELECTED DRAWING: Figure 1
