Title:
NICKEL PASTE AND NICKEL PASTE PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/047760
Kind Code:
A1
Abstract:
A nickel paste which undergoes substantially no change in viscosity over time and has excellent stability, and which is optimal for use in 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, dispersion shift accelerators, an organic solvent and a binder resin. The dispersion shift accelerators are a dispersion shift accelerator that has a specific negative ion surfactant structure, and an amine-based dispersion shift accelerator. The content of the dispersion shift accelerator that has the negative ion surfactant structure is 0.16-3.0 parts by mass per 100 parts by mass of the nickel powder, and the content of the amine-based dispersion shift accelerator is 0.2-4 times that of the dispersion shift accelerator that has the negative ion the surfactant structure. 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%.
