Electrically Conductive Dense and Porous Alumina with In‐Situ‐Synthesized Nanoscale Carbon Networks

Electrically conductive dense and porous alumina compacts are fabricated by sintering dried gel-cast alumina samples with a homogeneous gel-binder distribution under an argon atmosphere. Sintering at an optimal temperature of 1700 °C leads to the uniform formation of electrically conductive nanoscale graphitic conduits throughout the composite, as shown in the figure.
