Description
(D90/D10)1/2≧2 (1)
ここで、上記式(1)中、D90は体積基準の累積百分率90%相当粒子径であり、D10は体積基準の累積百分率10%相当粒子径である。
上記式(1)中、D90は体積基準の累積百分率90%相当粒子径であり、D10は体積基準の累積百分率10%相当粒子径である。
(a)異なる粒径分布を有するアルミニウム源粉末を混合する方法。たとえば、レーザ回折法により測定される、体積基準の累積百分率50%相当粒子径(D50)が0.5〜10μmの範囲内であるアルミニウム源粉末と、体積基準の累積百分率50%相当粒子径(D50)が10〜60μmの範囲内であるアルミニウム源粉末とを混合する方法を挙げることができる。
(b)粒径が比較的大きなアルミニウム源粉末を所定時間解砕する方法。たとえば、体積基準の累積百分率50%相当粒子径(D50)が15〜75μmの範囲内であるアルミニウム源粉末を所定時間解砕する方法を挙げることができる。
(c)焼成により酸化アルミニウムに導かれるアルミニウム源粉末を所定時間焼成する方法。たとえば、水酸化アルミニウム粉末を所定時間焼成する方法を挙げることができる。焼成により酸化アルミニウムに導かれるアルミニウム源粉末(たとえば、水酸化アルミニウム粉末)のD50は、5〜60μm程度であることが好ましい。
(d)粒径が比較的小さなアルミニウム源粉末を所定条件で造粒する方法。
(e)共沈法により、上記式(1)を満たすアルミニウム源粉末を得る方法。
チタン酸アルミニウム化率(AT化率)は、粉末X線回折スペクトルにおける2θ=27.4°の位置に現れるピーク〔チタニア・ルチル相(110)面〕の積分強度(IT)と、2θ=33.7°の位置に現れるピーク〔チタン酸アルミニウムマグネシウム相(230)面〕の積分強度(IAT)とから、下記式により算出した。
AT化率=IAT/(IT+IAT)×100(%)
得られたチタン酸アルミニウム系焼成体から、約4mm×4mm×50mmの試験片を切り出した。ついで、この試験片に対して、300℃/hの昇温速度で1100℃まで昇温し、同温度で48時間保持した後、300℃/hの降温速度で室温まで冷却する熱処理を施した。当該熱処理を行なう前のAT化率R0(%)と熱処理を行なった後のAT化率R(%)を上記方法により測定し、熱処理による焼成体中のチタンアルミニウムマグネシウム結晶の減少率として、下記式に基づき、耐熱分解率を求めた。
耐熱分解率(%)=(R/R0)×100
チタン酸アルミニウム系焼成体から、原料混合物の押し出し成形時の押出し方向に長さ50mm、幅5mm、厚さ5mm程度の直方体形状に切り出した。この切り出した焼成体の外表面を紙やすり(#1500)を用いて凹凸がなくなるまで研磨した。得られたサンプルの三点曲げ強度を、JIS R 1601に準拠した方法により測定した。
チタン酸アルミニウム系焼成体から、約4mm×4mm×10mmの試験片を切り出した。ついで、この試験片に対して、200℃/hの昇温速度で1000℃まで昇温し、直ちに室温(25℃)まで冷却する熱処理を施した。熱処理を施した試験片について、熱機械的分析装置(SIIテクノロジー(株)製 TMA6300)を用いて、室温(25℃)から1000℃まで600℃/hで昇温させた際の試験片の膨張率から、下記式に基づき、熱膨張係数〔K-1〕を算出した。
熱膨張係数〔K-1〕=試験片の膨張率/975〔K〕
ここで、試験片の膨張率とは、
(1000℃まで昇温させたときの試験片の体積−昇温前(25℃)における試験片の体積)/(昇温前(25℃)における試験片の体積)
を意味する。
JIS R1634に準拠した、水中浸漬によるアルキメデス法により、焼成体の水中重量M2(g)、飽水重量M3(g)および乾燥重量M1(g)を測定し、下記式により開気孔率を算出した。
開気孔率(%)=100×(M3−M1)/(M3−M2)
