摘要
PROBLEM TO BE SOLVED: To provide a method for dispersing an Ni powder having an extremely fine average primary particle size of ≤0.2 μm, preferably ≤0.1 μm, in a state close to a primary particle without inducing flocculation over a long period of time, even when such Ni powder is contained at a high concentration, and an Ni powder dispersion which is obtained thereby, has a good printability and applicability and is used as an ink, a paint, a conductive paste, etc.;SOLUTION: In the method, the Ni powder having an average primary particle size of ≤0.2 μm is dispersed in a solvent using a dispersing agent. Here, a cellulose acetate having a butyryl group content of 15-55 mass% and a polymerization degree of 75-440 is used as the dispersant.;COPYRIGHT: (C)2005,JPO&NCIPI
