Development of Cramics Nano-structures with Liquid Phase Crystal Growth

Abstract

Attention is being paid to the control of nanostructures for enhancement of ceramics performance. In particular, attention is focused on nanoparticles having anisotropic shapes such as nanosheets and nanoneedles. Further expectation is raised for oriented structures of nanoblocks which are oriented and integrated. In this review, I would like to introduce various nanostructures formed through control of crystal growth in aqueous solutions. SnO₂ nanosheet assembled films were developed in an aqueous solution. The nanosheets stood perpendicular to the substrate to form oriented structure. Additionally, the SnO₂ nanosheet assembled films had gradient structure. Morphology control was realized with precise control of crystal growth.
