Description
本実施例では、カルボン酸の種類およびマグネシウムに対するカルボニル基のモル比の影響について調べた。即ち、マグネシウム化合物ゾルの原料として、所定量の酢酸マグネシウム(水和物を含む)、塩化マグネシウム、硝酸マグネシウムの粉末を用意し、水に溶解させた。また、水酸化マグネシウムの粉末を水に投入、攪拌し、水酸化マグネシウム粒子を水に分散させた。これに対し、表1に示す所定のカルボン酸またはカルボン酸塩を、マグネシウムに対するモル比が表1に示す値になるよう、攪拌しながら投入し、さらに所定量のモノエタノールアミンをpHが9.5となるよう添加して攪拌した。得られた生成物の状態と、その平均粒子径を日本ルフト社製DT1200により測定し、その結果を表1に示した。また、それぞれの試料において、別途、マグネシウムとカルボン酸のモル比が1:1となるよう反応させたときの溶解度を求め、その結果を表1に示した。なお、表1において、*印を附した試料は、本発明の範囲外のものである。
本実施例では、クエン酸またはコハク酸を用いるときの水系溶媒のpHの影響について調べた。即ち、酢酸マグネシウム(水和物を含む)の粉末を用意し、水に溶解させた。これに表2に示すカルボン酸を、マグネシウム1モルに対するカルボニル基のモル比が表2に示す値になるよう攪拌しながら投入し、さらに水系溶媒のpH調整剤として表2に示す塩基性物質を、表2に示すpHになるよう添加して攪拌した。得られた生成物の状態と、その平均粒子径を表2に示した。なお、表1において、*印を附した試料は、本発明の範囲外のものである。
本実施例では、本発明のマグネシウム化合物ゾルと他の金属化合物ゾルを副成分としてセラミック原料を製造した。即ち、セラミック粉体としてチタン酸バリウムの粉体を用意し、これをボールミルにより水と混合し、チタン酸バリウム粉体を含むスラリーを得た。次に、本発明の実施例1の試料番号1のマグネシウム化合物ゾルを用意した。また、マグネシウム以外の金属元素を主成分とする金属化合物ゾルとして、ホルミウムにクエン酸の配位したホルミウムミセル粒子が水中に分散した、ホルミウム化合物ゾルを用意した。
