Description
表1に示すように、α−アルミナ(平均粒径:5.0μm、BET比表面積:0.8m2/g)、ベーマイト(平均粒径:0.1μm、BET比表面積:163m2/g)、酸化チタン(平均粒径:0.2μm)、高純度カオリン(平均粒径:3μm)を調合・混合することにより、アルミニウムチタネート化原料(AT化原料)を調製した。調製したAT化原料の100質量部に対して、有機バインダー(メチルセルロース、ヒドロキシプロピルメチルセルロース)を1.5質量部添加して、さらに混合・真空脱気した。得られた真空脱気した混合物を石膏型で鋳込み成形して、成形体を得た。得られた成形体を、表2に示した焼成温度でそれぞれ常圧焼成して、AT焼結体を得た。得られた各AT焼結体について、熱膨張係数を測定した。その結果を表2に示す。

表2に示すように、実施例1及び実施例2では、BET比表面積の大きいベーマイトをアルミニウム源として使用することにより、アルミニウムチタネートの本来の特性を損なうことなく、比較例と比較して、熱膨張係数を小さくすることができた。より低い焼成温度においても低い熱膨張係数を維持できた(また、実施例1及び実施例2では、比較例と比較して、熱膨張係数が小さいセラミック構造体を製造することができた)。
Claims (4)

- 前記アルミニウム源に、アルミナ及び/又は水酸化アルミニウムが更に含有される請求項1に記載のセラミック構造体の製造方法。
- 前記セラミック構造体が、65質量%以上のアルミニウムチタネートの結晶相から構成されている請求項1または2に記載のセラミック構造体の製造方法。
