The increasing availability of nanopowders and nanotubes combined with modern processing techniques is enabling the development of new multi-functional materials. This will be illustrated by ceramic - Carbon Nanotube (CNT) nanocomposites. The addition of relatively small amounts (<1 vol%) of CNTs can convert an insulating ceramic into a good electrical conductor. Alumina - CNT nanocomposites, having electrical conductivities upto 550 S/m were sintered using Spark Plasma Sintering (SPS). These materials provide a new envelope of mechanical properties. They offer the advantages of ceramics combined with good electrical and thermal conductivities. There are two critical steps in their processing: dispersion of the CNTs; and densification by sintering. To minimise any degradation of the CNT, the nanocomposites are sintered by rapid (300 ºC/min), pulsed electrical heating in a vacuum environment. Using this approach it is possible to densify nanocomposites at processing temperatures of >1800 ºC without significant degradation of the CNTs. - See more at: http://www.iom3.org/news/young-persons-lecture-competition-abstracts-london-local-heat#sthash.lsgXWw0G.dpuf
