Title:
NICKEL PASTE AND NICKEL PASTE PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/047761
Kind Code:
A1
Abstract:
A nickel paste which disperses nickel powder in a less-aggregated state and has excellent dry film density after coating, and which can be optimally used as a material for internal electrodes in multilayer ceramic capacitors, and a production method of said nickel paste are provided. This nickel paste contains at least a nickel powder, a dispersion shift accelerator, an organic solvent and a binder resin. The dispersion shift accelerator has a specific negative ion surfactant structure, and the content of the dispersion shift accelerator having the negative ion surfactant structure is 0.4-4.6 parts by mass per 100 parts by mass of the nickel powder. Further, the nickel concentration is 50-70 mass%, the viscosity is 8-150 Pa*s, and the water content measured by Karl Fischer's method is less than 1 mass%.
