Nanostructured Ceramics Obtained Under Extreme Conditions of Pressure and Temperature
Abstract
In this project we introduced a new approach to obtain nanostructured organic-inorganic ceramic materials using the sol-gel method combined with high-pressure technique to produce ceramics with multifunctional properties. We investigated hybrid nanostructured materials, exploring alumina, zirconia and silica systems using carbon nanotubes (CNTs) as nanofibers reinforcements. The main challenge in CNTs- reinforced ceramic nanocomposites is the uniform dispersion of CNTs into the ceramic matrix and to obtaining a good interface between the CNTs and the matrix. This step is fundamental and we were able to achieve that. It was produced powders of nanocomposite materials of CNT/ alumina and CNT/zirconia. This materials and its applications are the subject of two PhD Thesis, that should be finished by the middle of 2012. several works were already published on this matter and some were presented in International Meetings.
