NICKEL PARTICLE WITH DIELECTRIC PARTICLE, AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide nickel particles with dielectric particles in which the dielectric particles do not come off from the surface of the nickel particles easily even if a strong force such as shearing force is applied. SOLUTION: These are the nickel particles with the dielectric material particles in which the dielectric material particles are adhered to the surface of the nickel particles. The surface of the nickel particles with the dielectric material particles is covered by an organic layer. The organic layer is composed of oligomer or polymer of polymerizable monomer. It is preferable that the average primary particle diameter of the nickel particles is 30 nm to 300 nm, and that the average primary particle diameter of the dielectric particles is 3 nm to 30 nm. It is preferable that the nickel particles are obtained by using a reaction liquid containing nickel compound, polyol, and noble metal catalyst, and by reducing nickel ions in the reaction liquid.
