**Abstract**

This book chapter will describe the recent advancements in advanced carbonceramics based hybrid materials, enhanced properties and efficient applications. There are various fabrication methods, Firstly, authors will discuss a solvothermal/ hot-pressing method which is employed to fabricate hybrids composed of crosslinked γ-Al2O3 nanorods and reduced graphite oxide (rGO) platelets. After calcination and hot-press processing, monoliths of Al2O3-rGO hybrids are obtained with improved physical properties. It is found that the oxygen-containing groups on graphene oxide benefit to the adsorption of Al-(OC3H7)3 (aluminum isopropoxide), leading to the uniform dispersion of rGO with Al2O3 which is hydrolyzed from aluminum isopropoxide in solvothermal reactions. Further, this research methodology has been extended to another ceramics-graphene nanostructure assembly, i.e., silica-rGO hybrids, by optimizing experimental conditions for the hydrothermal and hot pressing process. This book chapter will be a significant contribution for the applications of ceramics-graphene assembly nanomaterials, which can be made by simple fabrication route and which can be further applied as electrolytes, catalysts, conductive, electrochemically active, and as dielectric materials for the high-temperature applications due to enhanced physical properties.
