| titleOfInvention | Method of preparing magnetic ink using magnetic powder and making the magnetic ink prepared by the same |
| abstract | The present invention comprises the steps of adding an acid to deionized water to prepare a mixed solution; Preparing a first solution by adding a metal precursor and an iron precursor to the mixed solution; Adding a basic solution to the first solution to prepare a second solution in the form of a pH-adjusted sol; Performing a sol-gel method on the second solution in the sol form to form a metal iron oxide powder; Heat-treating the metal iron oxide powder to form a heat-treated metal iron oxide powder whose color is changed; And mixing the heat-treated metal iron oxide powder and a fluid to produce a magnetic ink, and a method of manufacturing a magnetic ink, a magnetic ink produced thereby, and a magnetic printing method using the same. |
