COMPOSITION, GREEN SHEET, BURNED PRODUCT, AND GLASS CERAMIC SUBSTRATE
To provide a composition that can be used for producing a glass ceramic substrate excellent in strength and thermal conductivity.SOLUTION: A composition includes tabular alumina particles where mullite is contained in its surface layer, and a glass component. The composition is preferably used for producing a glass ceramic substrate. In an XPS analysis, the tabular alumina particles preferably have a molar ratio [Si]/[Al] of Si to Al of 0.15 or more. In an XRD analysis, the tabular alumina particles preferably have the ratio of the peak intensity of mullite observed when 2θ is between 26.2±0.2° to the peak intensity of a (104) surface of α-alumina observed when 2θ is between 35.1±0.2° of 0.02 or more.SELECTED DRAWING: None
【課題】強度及び熱伝導率に優れるガラスセラミックス基板の製造に用いることのできる、組成物を提供する。【解決手段】ムライトを表層に含む板状アルミナ粒子と、ガラス成分と、を含有する組成物。前記組成物は、ガラスセラミックス基板の製造に用いられることが好ましい。前記板状アルミナ粒子は、ＸＰＳ分析において、Ａｌに対するＳｉのモル比［Ｓｉ］／［Ａｌ］が０．１５以上であることが好ましい。前記板状アルミナ粒子は、ＸＲＤ分析において、２θが３５．１±０．２°に認められるα−アルミナの（１０４）面のピーク強度に対する、２θが２６．２±０．２°に認められるムライトのピーク強度の比が０．０２以上であることが好ましい。【選択図】なし
