Graphite transforms to nano-crystallite carbon during mixing which is favourable for the rapid formation of TiC second phase in the following SPS process. The composites exhibited a novel honeycomb-like cellular microstructure with the formation of 5–6 vol% fine TiC submicron grains interconnected in the titanium α/β matrix.

Sintering Anatase films deposited on graphite substrates were fired in air using an electric muffle furnace in the range 500-700 C. Graphite substrates were completely burnt off at 700C when fired in air, while samples fired at lower temperatures exhibited poor adhesion and substrate deterioration.

Cold Sintering

'Cold sintering' has been developed as a novel method of densification which uses a transient liquid phase, pressure and heat to achieve dense ceramics. This review explores the process of cold sintering and its potential to densify various ceramic materials and components at low temperatures (300C), primarily describing recent results at The University of Sheffield, UK.

The effect of sintering time, temperature, and graphene

However, few detailed studies exist on the effect of the process conditions such as sintering temperature (T S), time (t S), and a number of graphene nanoplatelets. Therefore, the effects of different sintering times ( t S = 60, 120, 180, 300 min), sintering temperatures ( T S = 550, 600, 630℃), and graphene addition (0.1, 0.3, 0.5 wt%) on apparent density and hardness were reported in
