“…22 However, due to the evaporation of FA during the initial sol-gel process and PFA during drying and calcination processes, a designed C/Ti ratio of 3 in the composition was found not sufficient to complete the carbothermal reaction. A complete oxidation of TiC to TiO 2 would result in a weight gain of 33.3%.…”

The graphene used in this research was casted into a sponge-like shape, composed of a three-dimensional (3D) network of graphene sheets. The sol-gel infiltration synthesis method allowed the formation of nanostructured ceramics inside the porous structure of graphene networks, thus forming composites. The compositions and microstructures of the Ti-O-C composites changed with the amount of the polymerizable carbon source (i.e. furfuryl alcohol (FA)) in the solution. A high carbon ratio was required to maintain the structure of the graphene network, as the graphene sheets could become a carbon source to react with TiO 2 resulting in a lamellar-shaped grain morphology. Samples after SPS showed some toughening effects, such as de-bonding, bridging and formation of microcracks. Vickers hardness, electrical resistivity and thermal conductivity were examined for the composites.

The comprehensive recovery of zinc and lead by carbothermal reduction of zinc dusts in vacuum was investigated by XRD, SEM and DTA-TG. Thermodynamics analysis indicates that it can reduce the critical carbothermal reduction temperature of zinc oxides and lead oxides to zinc and lead in vacuum condition. Experimental results demonstrate that pure zinc and lead are obtained with molar ratio of (PbO + ZnO) to C ranging from 1:1 to 1:3 at 850-1000 °C distillation reduction for 40-100 min when the system pressure is 20 Pa.
