CORE MATERIAL AND HEAT DISSIPATION SUBSTRATE
To provide a core material capable of obtaining both high isotropic heat dissipation and high strength.SOLUTION: A core material 10A includes a ceramic material including a filler. The filler is manufactured by mixing inorganic particles (fine alumina particles, etc.) with a reducer (carbon black dispersion), drying the dispersion to prepare granules and heating the granules at a temperature of 1500 to 1600°C for 10 hours in an argon atmosphere to grow a plurality of whiskers extended outside from the surface of the inorganic particle. The core material having high thermal conductivity is obtained by adding the filler to a glass component, mixing them, molding and laminating the sheet, pressing the laminate at 80 MPa and sintering the pressed laminate at 900°C for 1 hour in the atmospheres.SELECTED DRAWING: Figure 7
【課題】等方的な高放熱性と高強度が両立したコア材の提供。【解決手段】フィラーを含有するセラミック材料を含んでなるコア材１０Ａであって、前記フィラーは、無機粒子(微細アルミナ粒子等）を還元剤（カーボンブラック分散液）と混合し、次いで分散液を乾燥して顆粒を作製し、この顆粒を１５００から１６００℃の温度でアルゴン雰囲気下１０時間熱処理して無機粒子表面から外側へ延びる複数のウイスカーを成長させ、製造する。このフィラーをガラス成分に添加・混合し、シート成形、積層して８０ＭＰａでプレス後、大気中９００℃で１時間焼成することにより高熱伝導率のコア材を得る。【選択図】図７
