    Abstract: A multilayer ceramic capacitor that includes a ceramic body including a stack of a plurality of dielectric layers and a plurality of first and second internal electrodes; and first and second external electrodes provided at each of both end faces of the ceramic body. Each of the plurality of dielectric layers contain Ba, Ti, P and Si. The plurality of dielectric layers include an outer dielectric layer located on an outermost side in the stacking direction; an inner dielectric layer located between the first and second internal electrodes; and a side margin portion in a region where the first and second internal electrodes do not exist. In at least one of the outer dielectric layer, the inner dielectric layer and the side margin portion, the P and the Si segregate in at least one of grain-boundary triple points of three ceramic particles.

    Abstract: An inkjet ink that contains a functional particle having a BET-equivalent particle diameter of 50 to 1000 nm, a rheology-controlling particle having a BET-equivalent particle diameter of 4 to 40 nm, and an organic vehicle. The ink has a viscosity of 1 to 50 mPa·s at a shear rate of 1000 s−1. At a shear rate of 0.1 s−1, the ink has a viscosity equal to or higher than a viscosity η calculated using the following equation: η=(D)2×ρ/104/2+80 [where η is the viscosity (mPa·s) at a shear rate of 0.1 s−1, D is the BET-equivalent particle diameter (nm) of the functional particle, and ρ is the specific gravity of the functional particle].

    Abstract: A method for producing a composite oxide-coated metal powder that includes a first step of coating a metal powder with a metal oxide by a hydrolysis reaction of a water-soluble metal compound in an aqueous solvent, and a second step of turning the metal oxide into a composite oxide. In the first step, the water-soluble metal compound containing a tetravalent metal element dissolved in a solvent including at least water is added to a slurry including the metal powder dispersed in the solvent to deposit the metal oxide containing the tetravalent metal element and produce a metal oxide-coated metal powder slurry. In the second step, a solution or powder containing at least one divalent element is added to the metal oxide-coated metal powder slurry to react the metal oxide present on the surface of the metal powder with the divalent element, thereby providing the composite oxide-coated metal powder.
