SiC composites containing carbon nanotubes and oxide additives based on organoelementoxanes. Preparation by spark plasma sintering

摘要

Samples of a SiC composite with an oxide additive of eutectic composition produced from the organomagne-siumoxane-yttriumoxane-alumoxane oligomer (OMYA) and multi-walled carbon nanotubes (MWCNTs) were prepared by the spark plasma sintering (SPS). It is shown that the combined introduction of an oxide additive derived from OMYA together with MWCNTs significantly increases the fracture toughness and strength of the composite.
