Phase Formation and the Electrical Properties of YSZ/rGO Composite Ceramics Sintered Using Silicon Carbide Powder Bed

Fully stabilized zirconia/graphene composites are very promising advanced structural materials having mixed ion–electron conductivity for energy storage and conversion applications. The existing methods of the composite manufacturing have a number disadvantages that limit their practical use. Thus, search new sintering is an actively developing area. In this work, we report first time application SiC powder bed technique fully zirconia (YSZ) fabrication. reduced graphene oxide (rGO) was used as derivative. As result, well-formed ceramics with high density crystallinity, maximal microhardness 13 GPa values ionic up to 10−2 S/cm at 650 °C obtained. effects conditions rGO concentration on microstructure conductivities discussed in detail. suggested layered graphite/SiC/graphite allowed dense YSZ/rGO fabrication can become suitable alternative various ceramic matrix fabrication: both conventional non-equilibrium (SPS, flash sintering) approaches.
