  • Method of manufacturing a ceramic electronic part
    Patent number: 5561828
    Abstract: A method of manufacturing a ceramic electronic part includes the steps of: firing Pd electrodes or alloy electrodes containing Pd as a primary metal along with ceramics in the atmosphere in which Pd cannot be oxidized within the range (I) of oxidizing temperature of Pd in air; and firing the Pd electrodes or alloy electrodes along with the ceramics in air within the range (II) of deoxidizing temperature of PdO in air. The method can manufacture a ceramic electronic part, such as a multilayer ceramic capacitor, including Pd electrodes or alloy electrodes which contain Pd as a primary metal without forming internal defects inside the ceramic electronic part and reducing its properties.
