Abstract
Official abstract text for this publication.
[Problem] The aim of the present invention lies in providing a glass ceramic sintered compact in which dielectric loss in a high-frequency region is reduced, without any reduction in sintering density, and also in providing a wiring board employing same. [Solution] A glass ceramic sintered compact containing a glass component, a ceramic filler and a composite oxide, characterized in that the glass component is crystallized glass on which is deposited a diopside oxide crystal phase including at least Mg, Ca and Si, and the composite oxide includes at least Al and Co.
First claim
Opening claim text (preview).
The invention claimed is: 1. A glass ceramic sintered compact containing a glass component, a ceramic filler and a composite oxide, wherein the glass component is crystallized glass on which is deposited a diopside oxide crystal phase comprising at least Mg, Ca and Si; and the composite oxide comprises at least Al and Co. 2. The glass ceramic sintered compact according to claim 1 , wherein the composite oxide further comprises Ti. 3. The glass ceramic sintered compact according to claim 1 or 2 , wherein the content of said composite oxide is 0.05-1.5 mass % in terms of oxide equivalent. 4. The glass ceramic sintered compact according to any of claims 1 to 3 , wherein the ceramic filler is Al 2 O 3 . 5. A wiring board comprising an insulating base and a wiring conductor, wherein the insulating base comprises the glass ceramic sintered compact according to any of claims 1 to 4 .
