ンが挙げられる。酸化チタンとしては、例えば酸化チタン(IV)、酸化チタン(III)、酸化チタン(II)などが挙げられ、酸化チタン(IV)が好ましく用いられる。酸化チタン(IV)の結晶型としては、アナターゼ型、ルチル型、ブルッカイト型などが挙げられ、アモルファスであってもよく、より好ましくはアナターゼ型、ルチル型である。
により算出した。
酸化チタン(IV)粉末〔デュポン(株)、「R−900」〕28.9質量部、αアルミナ粉末〔住友化学(株)製、「AES−12」〕36.9質量部、マグネシアスピネル粉末4質量部、長石粉末〔福島長石、SiO2換算のシリコン含有量は72質量%、Al2O3換算のアルミニウム含有量は15質量%〕2.6質量部を混合して得られた前駆体混合物を乳鉢にて粉砕し、粉砕後の混合物から3gを秤取し、一軸プレス機により内径20mmの金型内で200kgf/cm2(19.6MPa)の成形圧力でプレス成形して成形体を得た。
1300℃での保持時間を8時間とした以外は実施例1と同様に操作してチタン酸アルミニウムマグネシウム成形体を得た。この成形体の熱膨張率は、0.8×10-6K-1であった。この成形体を解砕して得られたチタン酸アルミニウムマグネシウム粉末のAMT化率は100%であった。
1300℃に昇温したのち、同温度で保持することなく、直ちに1450℃まで昇温した以外は実施例1と同様に操作してチタン酸アルミニウムマグネシウム成形体を得た。この成形体の熱膨張率は、2.1×10-6K-1であった。この成形体を解砕して得られたチタン酸アルミニウムマグネシウム粉末のAMT化率は100%であった。
900℃まで昇温し、同温度で4時間保持した後、1450℃まで昇温した以外は実施例1と同様に操作してチタン酸アルミニウムマグネシウム成形体を得た。この成形体の熱膨張率は、2.0×10-6K-1であった。この成形体を解砕して得られたチタン酸アルミニウムマグネシウム粉末のAMT化率は100%であった。
1300℃に昇温したのち、同温度で保持することなく、直ちに1450℃まで昇温し、同温度を24時間保持することにより焼成した以外は実施例1と同様に操作してチタン酸アルミニウムマグネシウム成形体を得た。この成形体の熱膨張率は、1.9×10-6K-1であった。この成形体を解砕して得られたチタン酸アルミニウムマグネシウム粉末のAMT化率は100%であった。
