さらに、本発明は、本発明に従うベーマイト型結晶アルミナの製造方法に関する。
製造に当たっては、酸化アルミニウム水和物のスラリーにわずかなせん断効果を加えることが好ましい。本発明で言うわずかなせん断効果とは、回転速度0.5ないし3m/sで運転される撹拌機(たとえばプロペラ撹拌機)によって作られるせん断を意味する。スラリーに使用される酸化アルミニウム水和物の粒子径は1ないし12μmが好ましく、特に6ないし12μmが好ましい。
結晶子の大きさ=(K×λ×57.3)/(β×cosθ)
K(形状係数): 0.992
入(X線の波長): 0.154nm
β(装置に固有の線幅の広がり補正): 反射に依存
θ: 反射に依存
以下に述べるようにしてアルミニウムアルコラートを中性加水分解し、出発原料のアルミナスラリーを調製した。

120反射面の方が、020反射面より3.1nmだけ大きい。
比較例で述べた、Al2 O3を10ないし11重量%含有するpH9のアルミナスラリー500gを回分式反応装置に仕込んだ。反応装置の圧力を98℃の常圧とした。反応条件を調整した後、通常の摸拝機を使用し、摸拝速度1.6m/s、回転数500回転/分で16時間熟成した。比較例で説明した方法によって得られた結晶子の大きさは、120面で13.5nm、020面で12.1nmであった。
比較例で述べた、Al2 O3を10ないし11重量%含有するpH9のアルミナスラリー500gを回分式反応装置に仕込んだ。反応装置の圧力を3bar、110℃とした。反応条件を調整した後、通常の撹拌機を使用し、撹拌速度1.6m/s、回転数500回転/分で40時間熟成した。
