| 20090032780 | NICKEL PASTE - Nickel paste includes nickel powder, a resin binder and an organic solvent, wherein the nickel powder includes less than 100 ppm sulfur. This provides the nickel paste that the change in viscosity due to sulfur included in the paste can be preferably restrained by using nickel powder including extremely small amount of sulfur. Limitation of sulfur to the extremely small amount causes superior stability, and then, since kinds of solvents and resin binders are not limited, the change in viscosity can be preferably restrained with using the solvent that is hard to cause the chemical attack on the green sheet as described above. Thus, nickel paste that is hard to cause the chemical attack and the change in viscosity can be provided. | 02-05-2009 |
