COMPOSITE POWDER, GRANULAR POWDER, TABLET, SINTERED SHEET AND SINTERED BODY
To provide a composite powder that can be fired at 1000°C or lower, and has low dielectric properties in a high frequency region, and provide granular powder, a tablet, a sintered sheet and a sintered body.SOLUTION: A composite powder contains at least glass powder and alkaline-earth carbonate powder. The glass powder contains, as a glass composition, in mass%, SiO2 60-85%, B2O3 15-40%, R2O(Li2O+Na2O+K2O) 0.1-5.0%. The alkaline-earth carbonate powder is at least one selected from the group of MgCO3, CaCO3, SrCO3, BaCO3. Relative to 100 pts.mass of the glass powder, the alkaline-earth carbonate powder is 0.01-3.0 pts.mass.SELECTED DRAWING: None
【課題】１０００℃以下の温度で焼成でき、しかも高周波領域において、低い誘電特性を有する複合粉末、顆粒粉末、タブレット、シート焼結体及び焼結体を提供する。【解決手段】本発明の複合粉末は、少なくともガラス粉末とアルカリ土類炭酸塩粉末とを含む複合粉末であって、ガラス粉末が、ガラス組成として、質量％で、ＳｉＯ２６０〜８５％、Ｂ２Ｏ３１５〜４０％、Ｒ２Ｏ（Ｌｉ２Ｏ＋Ｎａ２Ｏ＋Ｋ２Ｏ） ０．１〜５．０％を含有し、アルカリ土類炭酸塩粉末が、ＭｇＣＯ３、ＣａＣＯ３、ＳｒＣＯ３、ＢａＣＯ３の群から選ばれる１種又は２種以上であり、ガラス粉末１００質量部に対して、アルカリ土類炭酸塩粉末を０．０１〜３．０質量部含むことを特徴とする。【選択図】なし
