Latest Patents

Ohara's latest patents focus on innovative formulations of conductive paste. One of his notable inventions involves a conductive paste that is included in the inner electrodes of a multilayer ceramic capacitor. This paste is fired and consists of a conductive metal powder, a ceramic powder, an organic solvent, and an organic binder. The conductive metal powder includes copper, and a portion of the ceramic powder is an oxide of an ABO type with a specific ionic radius. The ratio of the six-coordinate ionic radius of an A-site element in ABO to that of copper is maintained between 0.96 and 1.04. Another patent describes a similar conductive paste, which defines the inner electrodes of a multilayer ceramic capacitor and includes a conductive metal powder, ceramic powder, organic solvent, and organic binder. In this case, the ceramic powder is also an oxide of ABO type, with the ionic radius ratio being between 0.97 and 1.04. When nickel is included in the conductive metal powder, the oxide of ABO type may be NiTiO, MgTiO, or MnTiO.
