MANUFACTURING METHOD OF GRAPHITE COATED UNIFORM NANO MAGNETIC PARTICLE USING A HYDROTHERMAL SYNTHESIS CAPABLE OF IMPROVING CHEMICAL STABILITY AND MAGNETISM EFFECT

摘要

PURPOSE: A manufacturing method of graphite coated uniform nano magnetic particle using a hydrothermal synthesis is provided to obtain high yield nano magnetic particle by hydrothermally synthesizing saccharide with metal salt and heat-treating thereof.;CONSTITUTION: A manufacturing method of graphite coated uniform nano magnetic particle using a hydrothermal synthesis comprises the following steps: manufacturing metal precursor solution by dissolving the metal precursor in a solvent; manufacturing reaction solution by dissolving the saccharide in the metal precursor solution; manufacturing a nano magnetic particle which carbon ions are adsorbed on the surface by hydrothermal synthesizing the reaction solution; drying the nano magnetic particle; and forming a graphite coating layer by heat-treating the dried nano magnetic particle. The concentration of the metal precursor solution is 0.2-50M. The mass of the saccharide dissolved in the metal precursor solution is 25-200 parts by weight based on 100.0 parts by weight of the metal precursor.;COPYRIGHT KIPO 2012
