Abstract
Titanium carbide (TiC) particles were obtained in situ by a self-propagating high temperature synthesis (SHS) of wood dust with TiO2 and Mg. The reaction was carried out in a SHS reactor under static argon gas at the pressure of 0.5 MPa. The standard Gibbs energy minimization method was used to calculate the equilibrium composition of the reacting species. The effects of increasing Mg mole ratio to the precursor mixture of TiO2 and wood dusts were investigated. XRD and SEM analyses indicate a complete reaction of the precursors to yield TiC-MgO as a product composite. The synthesized composites were leached with 0.1M HCl acid solution to obtain TiC particles as final products.
