Tantalum carbide (TaC) ceramic has been widely studied because of its extremely high melting point of 3880 °C. However, TaC powder is extremely hard to sinter because of their strong covalent bonding and low self-diffusion coefficient [,,,, ]. The commonly adopted method to obtain highly dense TaC ceramics is the use of sintering additives.
