    • A multilayer ceramic part including dielectric ceramic layers and internal conductor layers is prepared by forming dielectric ceramic layers from an oxide system dielectric ceramic material having a sintering completion temperature between the melting point and the boiling point of the internal conductor. A pattern of internal conductor is formed on dielectric ceramic layers. The dielectric ceramic layers are placed one on another so as to sandwich the internal conductor pattern therebetween. The laminate is fired at or above the melting point of the internal conductor, optionally in an atmosphere having a controlled oxygen partial pressure. Since the dielectric ceramic material has an improved dielectric constant and dielectric loss and the internal conductor is densified and improved in surface property, the part is improved in resonator Q value and other properties. This minimizes the occurrence of defective parts in which the internal conductor is separated from the dielectric ceramic layer and minimizes a failure in the internal conductor layer.
    • 通过从具有在内部导体的熔点和沸点之间的烧结完成温度的氧化物系介电陶瓷材料形成介电陶瓷层来制备包括电介质陶瓷层和内部导体层的多层陶瓷部件。 在介电陶瓷层上形成内部导体的图形。 电介质陶瓷层一个接一个地放置在其间夹着内部导体图案。 层压体在内部导体的熔点以上或任意地在具有受控氧分压的气氛中烧制。 由于介电陶瓷材料具有改善的介电常数和介电损耗,并且内部导体致密化并且表面性能得到改善,所以该部件在谐振器Q值和其它性能方面得到改善。 这使得内部导体与介电陶瓷层分离的缺陷部件的发生最小化,并使内部导体层的故障最小化。
