Ceramic Composite Material Obtained by Spark Plasma Sintering Technology with Carbon Nanotubes

A nanocomposite based on corundum ceramic containing multiwall carbon nanotubes (to 50% by volume) as reinforcement was obtained by spark plasma sintering. The structure of the obtained material was investigated by means of optical and electronic microscopy. The elastic modulus and cracking resistance were measured and found to be three times greater than the corresponding values for pure aluminum oxide.
