Outline of Final Research Achievements

The mechanical and thermal properties of porous ceramics were examined theoretically and experimentally for alumina (Al2O3), mullite (3Al2O3-2SiO2), yttria-stabilized zirconia (YSZ, Y0.15Zr0.85O1.93) and silicon carbide (SiC) as a function of porosity. The compressive strength, Young's modulus and thermal conductivity of the porous oxides (Al2O3, 3Al2O3-SiO2, YSZ) or porous nonoxide (SiC) decreased with increasing porosity. On the other hand, the thermal expansion coefficient was independent of porosity, and agreed with the value for a dense ceramics with 0% porosity. These experimental results were well explained by the theoretical equations of mechanical and thermal properties derived for the microstructures with open or closed pores.

Academic Significance and Societal Importance of the Research Achievements

本研究グループでは、触媒担体やフィルターなどの多方面で用いられている多孔質セラミックスの強度、ヤング率、熱膨張係数、熱伝導度について、初期焼結モデルと立方体介在物粒子を含む二相系構造モデルからそれらの理論式を構築することに成功した。それらの理論式とアルミナ(Al2O3)、ムライト(3Al2O3-2SiO2)、イットリア安定化ジルコニア(YSZ, Y0.15Zr0.85O1.93)、炭化ケイ素(SiC)の多孔体を用いた実験結果を比較したところ、よく一致することが明らかとなった。これにより、多孔体の物性と構造の関係に対する理論的解釈が大きく前進することとなった。
