Low Temperature Preparation of Carbide Coated Carbon for Refractory Castable Applications

摘要

Titanium carbide (TiC) coated graphite flakes (GF) and carbon black (CB) powders were prepared at relatively low temperatures (750-950°C) using a novel molten salt synthesis technique.The in-situ formed TiC coatings were homogeneous and crack-free and their thicknesses could be readily controlled/tailored by simply adjusting the Ti/C ratio.Compared to their uncoated counterparts,as prepared TiC coated GF and CB showed much improved water-wettability/dispersivity and rheological properties,and thus could be potentially used to prepare carbon-containing refractory castables.
