  • Publication number: 20230073053
    Abstract: A method of manufacturing a dielectric for a capacitor and a dielectric for a capacitor manufactured thereby are provided. A dielectric for a capacitor is prepared by calcining a precursor mixture containing lead, lanthanum, zirconium, and titanium to produce calcined powder, adding additives including sodium, potassium, and the like to the powder, and sintering the mixture at a low temperature, whereby the dielectric has a high density and a large dielectric constant.

  • Patent number: 8865028
    Abstract: Disclosed herein is a ZnO-based varistor composition including zinc oxide (ZnO) as a main component and a calcium (Ca)-containing compound as an accessory component. The varistor composition provides excellent electrostatic discharge (ESD) characteristics because it has excellent physical properties, such as a nonlinear coefficient, a clamping voltage ratio, a surge absorbance and the like, and, particularly, does not include Bi2O3. Further, the varistor composition provides high work safety because it does not include Sb2O3 that is regulated for environmental purposes. Further, the varistor composition can reduce the manufacturing cost of a varistor because it does not Pr-based components that require high-temperature sintering and increase the manufacturing cost of a varistor. Particularly, the varistor composition has a low clamping voltage as well as a low capacitance.

  • Patent number: 8632924
    Abstract: Provided are a solid oxide fuel cell and a method of manufacturing the same. The solid oxide fuel cell in which at least one or more unit modules are stacked and integrated with each other includes first and second solid electrolyte layers in which each of the unit modules includes a plurality of fuel electrodes spaced a predetermined distance from each other and each having a strip shape and first and second supports each including a plurality of slits each having the same strip shape as that of each of the fuel electrodes. The first and second solid electrolyte layers overlap with each other on lower and upper sides of the first support so that the fuel electrodes face each other within the slits of the first support, and the second support overlaps with a lower side of the first or second solid electrolyte layer overlapping with the lower side of the first support so that the slits of the second support are disposed perpendicular to the slits of the first support.
