Abstrakt: Abstract—The influence of the graphene content (up to 2 wt %) and the sintering conditions on the temperature dependence of the electrical resistance of an Al2O3/graphene composite material in the temperature range 20–1600°C is studied. The composite material is fabricated from a mixture of initial powders by spark plasma sintering and hot pressing. The electrical resistance of the compacted material is found to depend on the pressing force and a heating method. The composite material prepared by hot pressing has the minimum electrical resistivity (0.9 Ω m). [ABSTRACT FROM AUTHOR]
