CERAMIC SINTERED BODY AND WIRING SUBSTRATE USING THE SAME
PROBLEM TO BE SOLVED: To provide a ceramic sintered body having high mechanical strength and chemical resistance, and excellent in high frequency characteristics, and to provide a wiring substrate using the same.SOLUTION: A ceramic sintered body comprises a composite phase of an alumina crystal phase 1a and a Mullite crystal phase 1b, as a main crystal phase 1, and contains a Kanoite crystal phase 5 in a grain boundary 3 of the main crystal phase 1. The alumina crystal phase 1a is surrounded with the Mullite crystal phase 1b spreading in a matrix. A wiring substrate includes: an insulating base constituted by the ceramic sintered body; and a conductor layer prepared at least on a surface of the insulating base.SELECTED DRAWING: Figure 1
【課題】機械的強度及び耐薬品性が高く、高周波特性に優れたセラミック焼結体とこれを用いた配線基板の提供。【解決手段】アルミナ結晶相１ａおよびムライト結晶相１ｂの複合相を主結晶相１とし、主結晶相１の粒界３にカノアイト系結晶相５を含むセラミック焼結体。アルミナ結晶相１ａはマトリックス状に広がったムライト結晶相１ｂに囲まれており、配線基板が、上記のセラミック焼結体によって構成される絶縁基体と、該絶縁基体の少なくとも表面に設けたられた導体層とを具備する配線基板。【選択図】図１
