- 以下の工程を含むことを特徴とする、高分散性の正方晶相チタン酸バリウムナノ粒子の製造方法。
1)テトラブチルチタネートを有機溶媒に溶解して溶液Aを得、氷酢酸にバリウム化合物を添加して溶解又は反応させて溶液Bを得、溶液Aと溶液Bを混合して、チタン及びバリウムを含むオルガノゾルを調製する。前記有機溶媒は、エチレングリコールモノメチルエーテル、エチレングリコールモノエチルエーテル、エチレングリコールモノブチルエーテル、エタノール、n-プロパノール、イソプロパノール、n-ブタノール、エチレングリコール及びプロピレングリコールのうちの1種である。
2)チタン及びバリウムを含むオルガノゾルと水溶性塩を混合し、静置または遠心分離して水溶性塩を沈降させ、上部の余分なオルガノゾルを除去して、チタン及びバリウムを含むオルガノゾルと水溶性塩の混合物を得る。
3)当該混合物を60℃~120℃に保温してゾル-ゲル転移を起こし、ゲルを乾燥させて、水溶性塩粒子の表面を乾燥ゲル膜で被覆する。
4)乾燥ゲル膜で被覆された水溶性塩を600℃以上、塩の融点以下で焼成し、乾燥ゲル膜がチタン酸バリウムナノ粒子に変化し、水溶性塩粒子の表面に分散して付着し、焼成物を形成する。
5)焼成物を水洗、乾燥し、正方晶相チタン酸バリウムナノ粒子を得る。 - 前記水溶性塩が硫酸カリウム、硫酸ナトリウム、塩化カリウムまたは塩化ナトリウムである、請求項1に記載の高分散性の正方晶相チタン酸バリウムナノ粒子の製造方法。
- 前記チタン及びバリウムを含むオルガノゾル中のチタンのモル濃度がO.01M~1Mの間であり、テトラブチルチタネート、バリウム化合物、氷酢酸のモル比が1:1:1~6である、請求項1に記載の高分散性の正方晶相チタン酸バリウムナノ粒子の製造方法。
- 前記バリウム化合物が酢酸バリウム、水酸化バリウム、硝酸バリウムまたは炭酸バリウムである、請求項1に記載の高分散性の正方晶相チタン酸バリウムナノ粒子の製造方法。
