STRUCTURE AND JOINED COMPOSITE
To provide a structure and a joined composite that can achieve improvement in thermal conductivity or flexural strength.SOLUTION: A structure includes: a β silicon nitride crystal phase; and a Y2MgSi2O5 N crystal phase. The structure gives an X-ray diffraction pattern by a θ-2θ method, the pattern having a ratio of a peak intensity of a (22-1) plane of the Y2MgSi2O5 N crystal phase to a peak intensity of a (200) plane of the β silicon nitride crystal phase, the peak intensity of the (200) plane being determined at a position of 2θ=27.0±1°, the peak intensity of the (22-1) plane being determined at a position of 2θ=30.3±1°, and the ratio being 0.001 or more and 0.01 or less.SELECTED DRAWING: Figure 2
【課題】熱伝導率又は曲げ強度を向上できる、構造体及び接合体を提供する。【解決手段】実施形態に係る構造体は、β型窒化珪素型結晶相及びＹ２ＭｇＳｉ２Ｏ５Ｎ型結晶相を含む。θ−２θ法によるＸ線回折パターンにおいて、２θ＝２７．０±１°に現れるβ型窒化珪素型結晶相の（２００）面のピーク強度に対する、２θ＝３０．３±１°に現れるＹ２ＭｇＳｉ２Ｏ５Ｎ型結晶相の（２２−１）面のピーク強度の比は、０．００１以上０．０１以下である。【選択図】図２
