What is Tantalum Carbide?Tantalum Carbide (TaC) is a hard, brittle refractory ceramic with good electrical conductivity. It is an additive in high-temperature ceramics and aerospace industries for aircraft and rockets. It is odorless and brown-gray. Tantalum carbide is widely used as a sintering additive in ultra-high temperature ceramics or as a ceramic reinforcement in high-entropy alloys due to its excellent physical properties in melting point, thermal conductivity, thermal shock resistance
