ZrO2–Y2O3 ceramic composite modified by multilayered graphene

Аннотация

The effect of introduction of multilayered graphene particles into a ceramic material based on zirconium dioxide, stabilized by 3 mol % of Y₂O₃, on the microstructure and properties of the composite is studied. The introduction of 1 vol % of graphene is found to result in the improvement of the crack stability of the ceramic matrix by nearly 1.7 times. The microstructure of the sintered composite is shown to be dependent on the type of surfactant used for dispersing of thermally expanded graphite.
