Abstract | To provide a resin composition in which the content of an alumina powder is high and a mixture containing the alumina powder and an uncured resin has good moldability in a production stage.SOLUTION: The resin composition contains a resin and an alumina powder. The alumina powder contains: first alumina particles having a particle diameter D50 of more than 100 μm and a BET specific surface area measured by a Krypton adsorption method of 0.085 m2/g or less; and second alumina particles having a particle diameter D50 of 0.1 μm or more and 1.0 μm or less.SELECTED DRAWING: None
【課題】アルミナ粉末の含有量が多い樹脂組成物であって、製造段階においては、アルミナ粉末と未硬化の樹脂とを含む混合物が、良好な成形性を有している樹脂組成物を提供する。【解決手段】樹脂と、アルミナ粉末とを含む樹脂組成物であって、前記アルミナ粉末は、粒径D50が100μm超で、クリプトン吸着法により測定されたBET比表面積が、0.085m2/g以下の第1のアルミナ粒子と、粒径D50が0.1μm以上1.0μm以下の第2のアルミナ粒子と、を含む、樹脂組成物。【選択図】なし |
