Preparation of nm-sized BaTiO_3 crystallites by a LTDS method using a highly concentrated aqueous solution

摘要

A low temperature direct synthesis method is useful for preparing nm-sized barium titanate (BaTiO_3) crystallites. However, its characterization revealed that in BaTiO_3 crystallites prepared by this method, there were many hydroxyl Groups and barium vacancies. This is because of the use of aqueous solutions as starting materials. To prepare BatiO_3 Crystallites with a hydroxyl group less, use of a highly concentrated aqueous solution must be required.
