Ceramic Nano Composites for Thermal Insulators
Year: 2014
Type: article
Abstract: In this research, nanopore composite had an effect on enhancing thermal property and mechanical property. The nanopore composite maintained the pore structure and enhanced mechanical property. Al2O3 xerogel was collapsed after heat treatment over 1000°C and they had weak mechanical strength because of pores. For maintenance of pore at high temperature and improvement of mechanical strength, Al2O3 whisker was hybridized. The Al2O3 whiskers in nanopore composite play the role of pillar during heat treatment. The mechanical property of Al2O3 xerogel was improved through complexation with Al2O3 whisker. The elastic modulus of nanopore composite increased 225 % from Al2O3 xerogel.
