Structure and properties of Al2O3/Graphene nanocomposite processed by spark plasma sintering

The ultrasonic dispersion and spark plasma sintering technique have been used to process Al2O3/Graphene nanocomposite (Al2O3/G) with 0-2wt.% graphene. The topography of fracture, microstructure, density, microhardness, Young modulus, electrical and thermal conductivity of Al2O3/G nanocomposite are investigated.
