Synthesis of nano-structured metal oxide ceramics from aqueous solutions
2) 研究の概要
Nature has succeeded in producing an impressive variety of inorganic functional structures with designed shapes and sizes on specific sites through a biologically controlled biomineralization process, usually near room temperature and in aqueous solutions. These structures are formed through template-assisted self-assembly. This mineralization process is usually accomplished under mild conditions in terms of low temperature (usually <100C) and normal pressure / atmosphere. This approach is an attractive alternative for the preparation of nano-structured ceramics.
Novel synthesis methods are required for small electroceramic devices. Chemical approaches in aqueous solutions are expected as the energy-saving process. We investigate chemical processes of thin films and nano/micro particles for semi conductive metal oxide ceramics.
